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.

If FEC is supported, the corresponding
DP_TP_CTL register bits have to be configured.

The driver has to program the FEC_ENABLE in DP_TP_CTL[30] register

Depending on the transcoder enum values to translate from transcoder to
the corresponding CHICKEN_TRANS register can easily break if we add a
new transcoder. Add an explicit mapping instead, by using helpers to
look up the register instance either by transcoder or port (since
unconveniently the registers have both port and transcoder specific
bits).

While at it also check for the correctness of GEN, port, transcoder. I
wasn't sure if psr2_enabled can only be set for GEN9+, but that seems to
be the case indeed (see setting of sink_psr2_support in
intel_psr_init_dpcd()).

v2 (Ville):
- Make gen9_chicken_trans_reg() internal to intel_psr.c.
- s/trans/cpu_transcoder/

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 device info offset arrays for unevenly spaced register offsets is
great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.

While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.

Remove unused old palette macros while at it.

The UV plane is the master plane that does all color correction etc.
It needs to be programmed with the dimensions for color plane 1 (UV).

The Y plane just feeds the Y pixels to it. Program the scaler from the
master only, and set PLANE_CTL_YUV420_Y_PLANE on the slave plane.

Changes since v1:
- Make a common skl_program_plane, and use it for both plane updates.
Changes since v2:
- Make color_plane explicit, to clarify skl_update_plane(). (Ville)

The first 3 planes (primary, sprite 0 and 1) have a dedicated chroma
upsampler to upscale YUV420 to YUV444 and the scaler should only be
used for upscaling. Because of this we shouldn't program the scalers
in planar mode if NV12 and the chroma upsampler are used. Instead
program the scalers like on normal planes.

Sprite 2 and 3 have no dedicated scaler, and need to program the
selected Y plane in the scaler mode.

Changes since v1:
- Make the comment less confusing.
Changes since v2:
- Fix checkpatch warning (Matt)
- gen10- -> Pre-gen11 (Ville)
- PS_SCALER_MODE_PACKED -> PS_SCALER_MODE_NORMAL. (Matt)

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.

    Reuse vma size field (Lionel)

v3: Restrict size opening parameter to values supported by HW (Chris)
