drm/i915: Add skl_check_nv12_surface for NV12
We skip src trunction/adjustments for
NV12 case and handle the sizes directly.
Without this, pipe fifo underruns are seen on APL/KBL.
v2: For NV12, making the src coordinates multiplier of 4
v3: Moving all the src coords handling code for NV12
to skl_check_nv12_surface
v4: Added RB from Mika
v5: Rebased the series. Removed checks of mult of 4 in
skl_update_scaler, Added NV12 condition in intel_check_sprite_plane
where src x/w is being checked for mult of 2 for yuv planes.
v6: Made changes to skl_check_nv12_surface as per WA#1106
