Rounding to the closest kHz seems like the better option that round
down or up when computing the alternate clock for CEA/HDMI modes.
It'll give us a slightly more accurate clock in some cases.
Not sure why I went for the down+up approach originally. Perhaps
I was thinking we can go back and forth betwen the two frequencies
without introducing errors, but round to closest still maintains
that property.

EDID detailed timings have a resolution of 10kHz for the pixel clock, so
they can't represent certain CEA/HDMI modes accurately. If we see a mode
coming in via detailed timings which otherwise matches one of the
CEA/HDMI modes except the clock is just a bit off, let's assume that the
intention was for that mode to be one of the CEA/HDMI modes and go ahead
and fix up the clock to match the CEA/HDMI spec exactly (well, as close
as we can get with the 1 kHz resolution we use).
This should help code that's looking for an exact clock match (eg. i915
audio N/CTS setup).

Compared to wrapping the final kref_put with dev->struct_mutex this
allows us to only acquire the offset manager look both in the final
cleanup and in the lookup. Which has the upside that no locks leak out
of the core abstractions. But it means that we need to hold a
temporary reference to the object while checking mmap constraints, to
make sure the object doesn't disappear. Extended the critical region
would have worked too, but would result in more leaky locking.
Also, this is the final bit which required dev->struct_mutex in gem
core, now modern drivers can be completely struct_mutex free!
This needs a new drm_vma_offset_exact_lookup_locked and makes both
drm_vma_offset_exact_lookup and drm_vma_offset_lookup unused.
v2: Don't leak object references in failure paths (David).
v3: Add a comment from Chris explaining how the ordering works, with
the slight adjustment that I dropped any mention of struct_mutex since
with this patch it's now immaterial ot core gem.

This removes the last depency of radeon for dev->struct_mutex!
Also the locking scheme for hyperz/cmask owners seems a bit unsound,
there's no protection in the preclose handler (and that never did hold
dev->struct_mutex while being called). So grab the same lock there,
too.
There's also all the checks in the cs checker, but since the overall
design seems to never stall for the previous owner I figured it's ok
if I leave this racy. It was racy even before I touched it after all
too.

Since SKL has universal planes, we should configure the sprite planes
and the primary plane the same. For the primary plane we do enable
the pipe gamma on the plane so do the same for the non-primary planes.
Without this, the pipe CRC values will be different for something
displayed on the primary plane and something displayed on a sprite
plane when the ARGB8888 format is used.

Some registers are, naturally, lost in gpu reset/suspend cycle.
And some registers, for example in display domain, are not subject
to gpu reset so they retain their contents.
As hang recovery triggers a reset, recoverable gpu hang can currently
flush out essential workarounds and cause havoc later on.
When register GEN8_GARBNTL is missing the WaEnableGapsTsvCreditFix:skl,
it can cause random system hangs [1]. This workaround was added in:
commit 245d96670d ("drm/i915:skl: Add WaEnableGapsTsvCreditFix")
But another set of system hangs were observed and the failure pattern
indicated that there was random gpu hang preceding the system hang [2].
This lead to the realization that we lose this workaround and BDW_SCRATCH1
on reset.
Add these workarounds setup in display init to skl/bxt ring init
where LRI workarounds are also setup. This way their setup is not
dependent on display side init.
