drm/i915/flipq: Implement Wa_18034343758

Implement the driver side of Wa_18034343758, which is supposed to
prevent the DSB and DMC from accessing registers in parallel, and
thus potentially corrupting the registers due to a hardware issue
(which should be fixed in PTL-B0).

The w/a sequence goes as follows:
DMC starts the DSB
| \
DMC halts itself | DSB waits a while for DMC to have time to halt
. | DSB executes normally
. | DSB unhalts the DMC at the very end
. /
DMC resumes execution

v2: PTL-B0+ firmware no longer has the w/a since the hw got fixed
v3: Do the w/a on all PTL for now since we only have the A0 firmware
binaries which issues the halt instructions unconditionally
v4: PTL DMC binaries do in fact have the A0 vs. B0 split, so skip
the w/a on PTL-B0+

drm/i915/flipq: Implement flip queue based commit path

Support commits via the flip queue (as opposed to DSB or MMIO).

As it's somewhat unknown if we can actually use it is currently
gated behind the new use_flipq modparam, which defaults to disabled.

The implementation has a bunch of limitations that would need
real though to solve:
- disabled when PSR is used
- disabled when VRR is used
- color management updates not performed via the flip queue

v2: Don't use flip queue if there is no dmc
v3: Use intel_flipq_supported()
v3: Configure PKG_C_LATENCY appropriately
Ignore INT_VECTOR if there is a real PIPEDMC interrupt
(nothing in the hw appears to clear INT_VECTOR)
v4: Leave added_wake_time=0 when flip queue isn't used, to
avoid needleslly increasing pkg_c_latency on lnl/ptl due
to Wa_22020432604. This is a bit racy though...
Use IS_DISPLAY_VER()

drm/i915/flipq: Provide the nuts and bolts code for flip queue

Provide the lower level code for PIPEDMC based flip queue.

We'll use the so called semi-full flip queue mode where the
PIPEDMC will start the provided DSB on a scanline a little
ahead of the vblank. We need to program the triggering scanline
early enough so that the DSB has enough time to complete writing
all the double buffered registers before they get latched (at
start of vblank).

The firmware implements several queues:
- 3 "plane queues" which execute a single DSB per entry
- 1 "general queue" which can apparently execute 2 DSBs per entry
- 1 vestigial "fast queue" that replaced the "simple flip queue"
on ADL+, but this isn't supposed to be used due to issues.

But we only need a single plane queue really, and we won't actually
use it as a real queue because we don't allow queueing multiple commits
ahead of time. So the whole thing is perhaps useless. I suppose
there migth be some power saving benefits if we would get the flip
scheduled by userspace early and then could keep some hardware powered
off a bit longer until the DMC kicks off the flipq programming. But that
is pure speculation at this time and needs to be proven.

The code to hook up the flip queue into the actual atomic commit
path will follow later.

TODO: need to think how to do the "wait for DMC firmware load" nicely
need to think about VRR and PSR
etc.

v2: Don't write DMC_FQ_W2_PTS_CFG_SEL on pre-lnl
Don't oops at flipq init if there is no dmc
v3: Adapt to PTL+ flipq changes (different queue entry
layout, different trigger event, need VRR TG)
Use the actual CDCLK frequency
Ask the DSB code how long things are expected to take
v3: Adjust the cdclk rounding (docs are 100% vague, Windows
rounds like this)
Initialize some undocumented magic DMC variables on PTL
v4: Use PIPEDMC_FQ_STATUS for busy check (the busy bit in
PIPEDMC_FQ_CTRL is apparently gone on LNL+)
Based the preempt timeout on the max exec time
Preempt before disabling the flip queue
Order the PIPEDMC_SCANLINECMP* writes a bit more carefully
Fix some typos
v5: Try to deal with some clang-20 div-by-zero false positive (Nathan)
Add some docs (Jani)
