To be able to do this we need to separately keep track of how many
crtcs need a given WRPLL and how many actually actively use it. The
common shared dpll framework already has all this, including massive
state readout and cross checking. Which allows us to do this switch in
a fairly small patch.

Mostly this patch is one big excersize in deleting code and asserts
which are no longer needed. Note that we still abuse the shared dpll
framework a bit since we call the enable/disable functions from the
crtc mode_set and off hooks. But changing the actual hardware sequence
will be done in the next step.
Note that besides the massive amount of changes in this patch the
places and order in which the low-level WRPLL code is called is
absolutely unchanged.

To make things a bit more manageable extract a new function for
reading out common ddi port state. This means a bit of duplication
between encoders and the core since both look at the same registers,
but doesn't seem worth to make a fuzz about.
We can also remove the state readout code in intel_ddi_setup_hw_pll_state.
That code is only called from the hardware take over and not the cross
check code, and only after the crtc state is reconstructed. So we can
rely on an accurate value of crtc->config.ddi_pll_sel already.
Compared to the old code also trust the hw state more and don't
special-case port A - we want to cross-check the actual-state, not
bake in our own assumptions about how this is supposed to all be
linked up.
v2: Make use of the read-out ddi_pll_sel in intel_ddi_clock_get.

Similar to how the ->crtc_mode_set hook should touch the hardware to
enable anything the ->crtc_off hook should disable anything in the
hardware. Otherwise runtime pm for dpms will not work.
Currently the only things left int the haswell_crtc_off hook is
disabling the ddi plls. We can't move the WRPLL enabling out yet
because the current ddi pll sharing code used by the haswell code
doesn't separately track active users and overall users. This must be
fixed by porting it to the generic shared display pll framework, which
is powerful enough.
But the SPLL source is only used by the crt encoder and so can be
moved already. We only need to make sure that the ddi port E is
already off, which hsw_fdi_disable does by calling
intel_ddi_post_disable.
With this the code reorg to shuffle hsw fdi/lpt specific code into a
new hsw-specific crt encoder type is now finally complete.

The call to intel_ddi_pll_enable in haswell_crtc_mode_set is the only
function that still touches the hardware state from the crtc mode_set
callback on hsw. Since the SPLL isn't ever shared we can easily take
it out into the hsw crt encoder functions.
Temporarily we'll loose a bit of WARN_ON coverage with this, but once
the WRPLLs are switched over that will be restored. For the SPLL
selection add a WARN in the hsw fdi link training code.

All the other checks also check hw state, so checking our software
refcounts for the plls looks a bit odd. Also this will simplify the
conversion over to the shared dpll framework, which itself has massive
amounts of checks to make sure that we never leave a display pll
enabled when we shouldn't.
So after that conversion we should stil have a good enough coverage of
asserts for entering pc8/runtime pm on hsw/bdw.

On HSW, the D_COMP register can be accessed through the mailbox (read
and write) or through MMIO on a MCHBAR offset (read only). On BDW, the
access should be done through MMIO on another address. So to account
for all these cases, create hsw_read_dcomp() with the correct
implementation for reading, and also fix hsw_write_dcomp() to do the
correct thing on BDW.
With this patch, we can now get back from the PC8+ state on BDW. We
were previously getting a black screen and lots of dmesg errors.
Please notice that the bug only happens when you actually reach the

which translates to that the address of the HWS must be below 256MiB,
which is conveniently the mappable aperture.
This also appears to be true (but not documented as so) for gen4 and
