The revert was due to the register write seemingly not sticking,
but the HW team has confirmed that this is because the

Here the wa is added with a mask of 0 since the register is WO.

Fix the TODO leftover in the code by changing the argument in MG_PLL
macros. The MG_PLL ids used to access the register values can be
converted from tc_port rather than port.
All these registers can use the TC port to calculate the right offsets
because they are only available for TC ports. The range (PORT_C onwards)
may not be stable and change from platform to platform. So by using the
TC id directly we avoid having to check for the platform in the "leaf
functions" and thus passing dev_priv around.
The helper functions were also renamed to use "tc" as prefix to make
them more generic.

To make vblank timestamps work better with the TV encoder let's
scale the pipe timings such that the relationship between the
TV active and TV blanking periods is mirrored in the
corresponding pipe timings.
Note that in reality the pipe runs at a faster speed during the
TV vblank, and correspondigly there are periods when the pipe
is enitrely stopped. We pretend that this isn't the case and
as such we incur some error in the vblank timestamps during
the TV vblank. Further explanation of the issues in a big
comment in the code.
This makes the vblank timestamps good enough to make
i965gm (which doesn't have a working frame counter with
the TV encoder) report correct frame numbers. Previously
you could get all kinds of nonsense which resulted in
eg. glxgears reporting that it's running at twice the
actual framerate in most cases.

SFC (Scaler & Format Converter) units are shared between VD and VEBoxes.
They also happen to have separate reset bits. So, whenever we want to reset
one or more of the media engines, we have to make sure the SFCs do not
change owner in the process and, if this owner happens to be one of the
engines being reset, we need to reset the SFC as well.
This happens in 4 steps:
1) Tell the engine that a software reset is going to happen. The engine
will then try to force lock the SFC (if currently locked, it will
remain so; if currently unlocked, it will ignore this and all new lock
requests).
2) Poll the ack bit to make sure the hardware has received the forced
lock from the driver. Once this bit is set, it indicates SFC status
(lock or unlock) will not change anymore (until we tell the engine it
is safe to unlock again).
3) Check the usage bit to see if the SFC has ended up being locked to
the engine we want to reset. If this is the case, we have to reset
the SFC as well.
4) Unlock all the SFCs once the reset sequence is completed.
Obviously, if we are resetting the whole GPU, we don't have to worry
about all of this.

Although CNP names this field "Counter Fraction", what we write to the
register is really the denominator for the fractional part of the
divider, not the fractional part (and the field description even says
that). The ICP spec renamed the field to "Counter Fraction
Denominator", which makes a lot more sense. Use the more complete ICL
naming because we will merge the CNP and ICP functions into a single
one, which will introduce the concept of the numerator. That will make
a lot more sense when you read the "num/frac = den" calculation.

The way our hardware is designed doesn't seem to let us use the
MI_RECORD_PERF_COUNT command without setting up a circular buffer.
In the case where the user didn't request OA reports to be available
through the i915 perf stream, we can set the OA buffer to the minimum
size to avoid consuming memory which won't be used by the driver.
v2: Simplify oa buffer size exponent selection (Chris)
Reuse vma size field (Lionel)
v3: Restrict size opening parameter to values supported by HW (Chris)
v4: Drop out of date comment (Matt)
Add debug message when buffer size is rejected (Matt)
