drm/edid: Fix up clock for CEA/HDMI modes specified via detailed timings
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).

drm: rcar-du: Fix plane state free in plane reset handler
The plane reset handler frees the plane state and allocates a new
default state, but when doing so attempt to free the plane state using
the base plane state pointer instead of casting it to the
driver-specific state object that has been allocated. Fix it by using
the rcar_du_plane_atomic_destroy_state() function to destroy the plane
state instead of duplicating the code.
Since commit a483dcbfa21f919c ("ARM: shmobile: lager: Remove legacy
board support"), R-Car Gen2 SoCs are only supported in generic DT-only
ARM multi-platform builds. The driver doesn't need to match platform
devices by name anymore, hence remove the corresponding
platform_device_id entry.
we've forgotten to do the plane->old_fb refcount dance for
pan_display_atomic, which can result in refcount leaks if the current
configuration is not from fbcon. Which apparently can happen when
vt-switching - fbcon does a pan first before a set_par.
OCD-align function parameters while at it.
v2: Actually git add the OCD.

drm/gem: Use kref_get_unless_zero for the weak mmap references
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.

migrated away from, allowing us to simplify the code.

needing the handler to be re-entered each time.

before attempting to read the EDID, no matter where the EDID read request
came from.

drm/nouveau/bios: fix OF loading
Currently OF bios load fails for a few reasons:
- checksum failure
- bios size too small
- no PCIR header
- bios length not a multiple of 4
In this change, we resolve all of the above by ignoring any checksum
failures (since OF VBIOS tends not to have a checksum), and faking the
PCIR data when loading from OF.

drm/nouveau/fbcon: take runpm reference when userspace has an open fd
We need to do this in order to prevent accesses to the device while it's
powered down. Userspace may have an mmap of the fb, and there's no good
way (that I know of) to prevent it from touching the device otherwise.
This fixes some nasty races between runpm and plymouth on some systems,
which result in the GPU getting very upset and hanging the boot.
