drm/i915: Calculate ILK-style watermarks during atomic check (v3)
Calculate pipe watermarks during atomic calculation phase, based on the
contents of the atomic transaction's state structure. We still program
the watermarks at the same time we did before, but the computation now
happens much earlier.
While this patch isn't too exciting by itself, it paves the way for
future patches. The eventual goal (which will be realized in future
patches in this series) is to calculate multiple sets up watermark
values up front, and then program them at different times (pre- vs
post-vblank) on the platforms that need a two-step watermark update.
While we're at it, s/intel_compute_pipe_wm/ilk_compute_pipe_wm/ since
this function only applies to ILK-style watermarks and we have a
completely different function for SKL-style watermarks.
Note that the original code had a memcmp() in ilk_update_wm() to avoid
calling ilk_program_watermarks() if the watermarks hadn't changed. This
memcmp vanishes here, which means we may do some unnecessary result
generation and merging in cases where watermarks didn't change, but the
lower-level function ilk_write_wm_values already makes sure that we
don't actually try to program the watermark registers again.
v2: Squash a few commits from the original series together; no longer
leave pre-calculated wm's in a separate temporary structure since
it's easier to follow the logic if we just cut over to using the
pre-calculated values directly.

drm/i915: Determine I915_MAX_PLANES from plane enum
Let the compiler figure out what I915_MAX_PLANES is from 'enum plane' so
that we don't need a separate #define.
While we're at it, add the cursor plane to the enum. This will cause
I915_MAX_PLANES to now include the cursor plane in its count (it didn't
previously). This change is safe since we currently only use this
value in array declarations (never in the actual code logic); we just
wind up allocating slightly more memory than we need to. A followup
patch will cause various parts of the code to start using the extra
array element where appropriate.
(This patch probably should have been squashed with the followup patch,
but I couldn't figure out how to get Coccinelle to modify enum
declarations...)

drm/i915: Don't forget to mark crtc as inactive after disable
we added extra watermark updates to all of the .crtc_disable()
entrypoints to avoid problems problems with system resume on SKL. Those
disable entrypoints are currently called in just two places in the
driver: intel_atomic_commit (i.e., during a modeset) and
intel_crtc_disable_noatomic (which is called during hardware readout).
It seems that this extra watermark recalculation should only be
important in the latter case (which happens during a resume operation);
the former case should always have appropriate watermark programming
happening at other points in the modeset sequence.
Let's move the watermark update out of the .crtc_disable() entrypoints
and place it directly in intel_crtc_disable_noatomic() so that it only
happens on S3 resume and not during a regular modeset (since the
existing watermark handling should properly update watermarks during
normal atomic commits).

drm/i915: Always use crtc_ timings when dealing with adjustead_mode
The adjustead_mode crtc_ timings are what we will program into the hardware,
so it's those timings we should be looking practically everywhere.
The normal and crtc_ timings should differ only when stere doubling is
used. In that case the normal timings are the orignal non-doubled
timigns, and crtc_ timings are the doubled timings used by the hardware.
The only case where we continue to look at the normal timings is when we
pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC.
drm_edid keeps the modes aronund in the non-double form only, so it
needs the non-double timings to match against.

Dmc will restore the csr program except DC9, cold boot,

intel_csr_load_program() function is used to load the firmware
data from kernel memory to csr address space.
All values of csr address space will be zero if it got reset and
the first byte of csr program is always a non-zero if firmware
is loaded successfuly. Based on hardware status will load the
firmware.
Without this condition check if we overwrite the firmware data the
counters exposed for dc5/dc6 (help for debugging) will be nullified.
Note: Above commit message seems to be confused and the real problem
apparently going on is that for suspend-to-idle and system standby the
firmware survives (it's like runtime pm), but it doesn't for
suspend-to-mem and hibernate-to-disk. All the other talking about DC9
and pci reset are irrelevant for the path touched here (only driver
load and system resume functions) and might not be true statements.
