Remove DRM_SCHED_PRIORITY_LOW, as it was used
in only one place.
Rename and separate by a line
DRM_SCHED_PRIORITY_MAX to DRM_SCHED_PRIORITY_COUNT
as it represents a (total) count of said
priorities and it is used as such in loops
throughout the code. (0-based indexing is the
the count number.)
Remove redundant word HIGH in priority names,
and rename *KERNEL* to *HIGH*, as it really
means that, high.
v2: Add back KERNEL and remove SW and HW,
in lieu of a single HIGH between NORMAL and KERNEL.
