We mostly care about the plane type, because sometimes the driver may
do silly things when only a cursor is enabled for example, so we reduce
the number of tests. This puts an upper bound on the number of plane
combinations being tested, which is nice for gen11.

Changes since v1:
- Make 2 groups for overlay planes, and randomly put planes in either group.
