Fixes for 4.16. A bit bigger than I would have liked, but most of that
is DC fixes which Harry helped me pull together from the past few weeks.
Highlights:
- Fix DL DVI with DC
- Various RV fixes for DC
- Overlay fixes for DC
- Fix HDMI2 handling on boards without HBR tables in the vbios
- Fix crash with pass-through on SI on amdgpu
- Fix RB harvesting on KV
- Fix hibernation failures on UVD with certain cards

In dce110, the plane configuration is such that plane 0
or the primary plane should be rendered with only RGB data.
This patch adds the validation to ensure that no video data
is rendered on plane 0.

HW Engineer's Notes:
During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
VGA_TEST_ENABLE, to leave it in the same state as before.

While checking plane states for updates during atomic check, we create
dc_plane_states in preparation. These dc states should be freed if
something errors.
Although the input transfer function is also freed by
dc_plane_state_release(), we should free it (on error) under the same
scope as where it is created.

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK
If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.
Solution is to program the cursor while still locked.

The below commit
"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"
introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.
This change leads to BUG hit while performing atomic commit on amd driver.
As a fix this patch ensures that we disable the CRTC's with NULL FB by returning
-EINVAL and hence triggering fall back to the old behavior and turning off the
crtc in atomic_remove_fb().
V2: Added error check for plane_state and removed sanity check for crtc.

amdgpu_dm_atomic_check() is used to validate the entire configuration of
planes and crtc's that the user space wants to commit.
However amdgpu_dm_atomic_check() depends upon DRM_MODE_ATOMIC_ALLOW_MODESET
flag else its mostly dummy.
Its not mandatory for the user space to set DRM_MODE_ATOMIC_ALLOW_MODESET,
and in general its not set either along with DRM_MODE_ATOMIC_TEST_ONLY.
Considering its importantance, this patch defers the allow_modeset check
in dm_update_planes_state(), so that there shall be scope to validate
the configuration sent from user space, without impacting the population
of dc/dm related data structures.
