PCH_NONE to simplify code.
Also make sure that intel_pch_type() knows all the PCH ids returned by
intel_virt_detect_pch(). Loudly fail if this isn't the case; this

On SKL+ the dst colorkey must be configured on the lower
plane that contains the colorkey. This is in contrast to
most earlier platforms where the dst colorkey is configured
on the plane above.
The hardware will peform dst keying only between two immediately
adjacent (in zorder) planes. Plane 2 will be keyed against plane 1,
plane 3 againts plane 2, and so on. There is no way to key arbitrary
planes against plane 1. Thus offering dst color keying on plane 3+
is pointless. In fact it can be harmful since enabling dst keying on
more than one plane on the same pipe leads to only the top-most of
the planes performing the keying. For any plane lower in zorder the
dst key enable is simply ignored.
v2: s/plane 0/plane 1/ etc. since the hw plane names start from 1

There is a problem with kbl up to rev E0 where a heavy
memory/fabric traffic from adjacent engine(s) can cause an engine
reset to fail. This traffic can be from normal memory accesses
or it can be from heavy polling on a semaphore wait.
For engine hogging causing a fail, we already fallback to
full reset. Which effectively stops all engines and thus
we only add a workaround documentation.
For the semaphore wait loop poll case, we add one microsecond
poll interval to semaphore wait to guarantee bandwidth for
the reset preration. The side effect is that we make semaphore
completion latencies also 1us longer.

As part of our GEM initialisation now, we send a request to the hardware
in order to record the initial GPU state. This coupled with deferred
idle workers, makes aborting on error tricky. We already have the
mechanism in place to wait on the GPU and cancel all the deferred
workers for suspend, so let's reuse it during the error teardown. It is
already used in places for later init error handling, but doing so at
this point is slightly ugly due to the mutex dance (it's ok, the module
load is still single threaded).

As Chris has discovered on his Ivybridge, and later automated test runs
have confirmed, on most of our platforms hrtimer faced with heavy GPU load
can occasionally become sufficiently imprecise to affect PMU sampling
calculations.
This means we cannot assume sampling frequency is what we asked for, but
we need to measure the interval ourselves.
This patch is similar to Chris' original proposal for per-engine counters,
but instead of introducing a new set to work around the problem with
frequency sampling, it swaps around the way internal frequency accounting
is done. Instead of accumulating current frequency and dividing by
sampling frequency on readout, it accumulates frequency scaled by each
period.

One thing we didn't really understand about the OA report is that the
ContextID field (dword 2) is copy of the context descriptor (dword 1).
On Gen8->10 and without using GuC we didn't notice the issue because
we only checked the 21bits of the ContextID field in the OA reports
which matches exactly the hw_id stored into the context descriptor.
When using GuC submission we have an issue of a non matching hw_id
because GuC uses bit 20 of the hw_id to signal proxy submission. This
change introduces a mask to compare only the relevant bits.
On ICL the context descriptor format has changed and we failed to
address this. On top of using a mask we also need to shift the bits
properly.

PLLs are the source clocks for the DDIs so in order
to determine the ddi clock we need to check the PLL
configuration.
This gets a little tricky for ICL since there is
no register bit that maps directly to the link clock.
So this patch creates a separate function in intel_dpll_mgr.c
to obtain the write array PLL Params and compares the set
pll_params with the table to get the corresponding link
clock.
v2:
- Fix the encoder type check (DK).
- Improve our error checking, return a sane value (Mika, Paulo).
- Fix table entries (Paulo).

DFLEXDPMLE register is required to tell the FIA hardware which
main links of DP are enabled on TCC Connectors. FIA uses this
information to program PHY to Controller signal mapping.
This register is applicable in both TC connector's Alternate mode
as well as DP connector mode.
v2:
* Remove _ICL prefix since the reg is first introduced
in ICL (Paulo)
* s/ICL/icl in commit message (Lucas)

Add and enum for TC ports and auxiliary functions to handle them.
Icelake brings a lot of registers and other things that only apply to
the TC ports and are indexed starting from 0, so having an enum for
tc_ports that starts at 0 really helps the indexing.
This patch is based on previous patches written by Dhinakaran Pandiyan
and Mahesh Kumar.

Let's not take any chances by using a shortcut to mark the objects as in
the CPU domain upon freezing (all pages will be written to disk and so
on restore all objects will start from the CPU domain). Currently, we
simply mark the objects as being in the CPU domain, bypassing the
flushes. Let's call the full domain transfer function so that we have
less special case code (and symmetry with the suspend path) even though
it will be mostly redundant.

As we have already suspended the device, this should be a no-op except
for marking that all writes are indeed complete. The downside is that
we then have to walk all the lists of objects for what should be a no-op
(in some cases they will be mmio read to ensure the GGTT writes are
indeed flushed, and clflushes to ensure that cpu writes are in memory).
It seems prudent and the safer course for us to ensure all writes are
flushed to memory before suspend.

Set up the SKL+ scaler initial phase registers correctly. Otherwise
we start fetching the data from the center of the first pixel instead
of the top-left corner, which obviously then leads to right/bottom edges
replicating data excessively as the data runs out half a pixel too soon.
