Exynos atomic commit procedures already does this job of waiting for
pending updates to finish, that means using pending_flip_queue is
pointless now because the disable CRTC procedure will never happen
during a page_flip.

Add infrastructure to wait for all planes updates to finish by using
an atomic_t variable to track how many pending updates we are waiting
plus a wait_queue for the wait part.
It also changes vblank behaviour and keeps it enabled for all types
of updates

The atomic modesetting interfaces supports async commits that should be
implemented by the drivers. If drm core requests an async commit
exynos_atomic_commit() will now schedule a work task to run the update later.
It also serializes commits that needs to run on the same crtc, putting the
following commit to wait until the current one is finished.

fimd_update_plane() programs BUF_START[win] and during the update
BUF_START[win] is copied to BUF_START_S[win] (its shadow register)
and starts scanning out, then it raises a irq.
The fimd_irq_handler, in the case we have a pending_fb, will check
the fb value was copied to START_S register and finish the update
in case of success.

The current code was ignoring the end of update for all overlay planes,
caring only for the primary plane update in case of pageflip.
This change adds a change to start to check for pending updates for all
planes through exynos_plane->pending_fb. At the start of plane update the
pending_fb is set with the fb to be shown on the screen. Then only when to
fb is already presented in the screen we set pending_fb to NULL to
signal that the update was finished.

SKL-Y can now use the same programming for all VccIO values after an
adjustment to I_boost. SKL-U DP table adjustments.
1. Remove SKL Y 0.95V from "SKL H and S" columns in all tables. The
other SKL Y column removes the "0.85V VccIO" so it now applies to all
voltages.
2. DP table changes SKL U 400mV+0db dword 0 value from 2016h to 201Bh.
3. DP table changes SKL U 600mv+0db dword 0 value from 2016h to 201Bh.
4. DP table increases I_boost to level 3 for SKL Y 400mv+9.5db.
v2: Fix compilation warnings as pointed by Paulo.

VBT version 196 increased the size of common_child_dev_config. The
parser code assumed that the size of this structure would not change.
The modified code now copies the amount needed based on the VBT version,
and emits a debug message if the VBT version is unknown (too new); since
the struct config block won't shrink in newer versions it should be
harmless to copy the maximum known size in such cases, so that's what we
do, but emitting the warning is probably sensible anyway.
In the longer run it might make sense to modify the parser code to use a
version/feature mapping, rather than hardcoding things like this, but
for now the variants are fairly manageable.
This fixes a regression introduced in
