drm/i915: Sprinkle some FIXMEs about TGL+ DSI transcoder timing mess
The DSI code has some local hacks to program TRANS_VBLANK on
TGL+ (ICL DSI transcoders didn't have this register). That
will not work when we need to start using the delayed vblank
(for DSB purposes). Too lazy to figure out what the is going
on there, so just sprinkle FIXMEs in the hopes someone else
will spot them eventually.
v2: Only TRANS_{HBLANK,SET_CONTEXT_LATENCY} still no not

drm/i915: Configure TRANS_SET_CONTEXT_LATENCY correctly on ADL+
On TGL VBLANK.VBLANK_START was the mechanism by which we can
delay the pipe's internal vblank in relation to the transcoder's
vblank. On ADL+ that no longer does anything. Instead we must
now use the new TRANS_SET_CONTEXT_LATENCY register. Program it
accordingly.
And since VBLANK.VBLANK_START is no longer used by the hardware
on ADL+ let's just zero it out to make it stand out in register
dumps. Seeing the zeroed value should hopefully remind people
to check the other register instead.

drm/i915: Copy highest enabled wm level to disabled wm levels for gen >= 9
There was a specific SW workaround requested, which should prevent
some watermark issues happening, which requires copying highest
enabled wm level to those disabled wm levels(bit 31 is of course
still needs to be cleared).
This is related to different subsystems like PSR and others, which
may still consult a low power wm values ocassionally, despite those
are disabled. For that reason we need to keep sane values in
correspondent registers, even when those are disabled.

0349c41b0596 ("drm/i915/hwmon: Enable PL1 power limit") is incorrect and
caused a major regression on ATSM. The change enabled the PL1 power limit
but FW sets the default value of the PL1 limit to 0 which implies HW now
works at minimum power and therefore the lowest effective frequency. This
means all workloads now run slower resulting in even GuC FW load operations
timing out, rendering ATSM unusable.

drm/i915: Don't do the WM0->WM1 copy w/a if WM1 is already enabled
Due to a workaround we have to make sure the WM1 watermarks block/lines
values are sensible even when WM1 is disabled. To that end we copy those
values from WM0.
However since we now keep each wm level enabled on a per-plane basis
it doesn't seem necessary to do that copy when we already have an
enabled WM1 on the current plane. That is, we might be in a situation
where another plane can only do WM0 (and thus needs the copy) but
the current plane's WM1 is still perfectly valid (ie. fits into the
current DDB allocation).
Skipping the copy could avoid reprogramming the plane's registers
needlessly in some cases.
