drm/i915: Check pipe source size when using skl+ scalers
[ Upstream commit d944eafed618a8507270b324ad9d5405bb7f0b3e ]
The skl+ scalers only sample 12 bits of PIPESRC so we can't
do any plane scaling at all when the pipe source size is >4k.
Make sure the pipe source size is also below the scaler's src
size limits. Might not be 100% accurate, but should at least be
safe. We can refine the limits later if we discover that recent
hw is less restricted.
