VF drivers can only use GuC-based TLB invalidation, as they don't

any explicit TLB invalidation before enabling CTB communication,
as there will be an implicit GGTT TLB invalidation issued by the
GuC itself as part of MMIO-based action handling.

Use the suspend encoders helper which is also used by the i915 driver.
This fixes an issue in the xe driver where the encoder
suspend_complete() hook is not called and was an overlook when this hook
was added in commit b61fad5f7e5d ("drm/i915/tc: Call TypeC port
flush_work/cleanup without modeset locks held") for i915, but not added
to the xe driver (which was still in a separate source tree at the above

The formula of Coverage alpha blending is:
dst.a = dst.a * (0xff - src.a * SCA / 0xff) / 0xff
+ src.a * SCA / 0xff
dst.a: destination alpha
src.a: pixel alpha
SCA : plane alpha
When SCA = 0xff, the formula becomes:
dst.a = dst.a * (0xff - src.a) + src.a
This patch is to set the destination alpha (background) to 0xff:
- When dst.a = 0 (before), dst.a = src.a
- When dst.a = 0xff (after) , dst.a = 0xff * (0xff - src.a) + src.a
According to the fomula above:
- When src.a = 0 , dst.a = 0
- When src.a = 0xff, dst.a = 0xff
This two cases are just still correct. But when src.a is
between 0 and 0xff, the difference starts to appear

CONST_BLD must be enabled for XRGB formats although the alpha channel
can be ignored, or OVL will still read the value from memory.
This error only affects CRC generation.

9-bit alpha (max=0x100) is designed for special HDR related
calculation, which should be disabled by default.
Change the alpha value from 0x100 to 0xff in 8-bit form.

As we extend the use of DSB for critical pipe/plane register
programming, it'll be nice to have an escape valve at hand,
in case things go very poorly. To that end, add a i915.enable_dsb
modparam by which we can force the driver to take the pure mmio
path instead.
