[Intel-gfx] [PATCH 0/9] skl+ cursor DDB allocation fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

This series mainly fixes the DDB allocation for cursor on skl+.
Currently that is totally busted.

In an effort to optimize cursor behaviour I'm also changing
which plane watermarks we choose to disable. This was inspired
by the 2x-cursor-vs-flip fails, but I don't see how this would
help there as that test should not be changing the plane
configuration in any significant way during the test (it should
only move the cursor and perform page flips).

And finally I sprinkled the usual amount of cleanups
on top.
