drm/xe: Fix xe_mmio_rmw32 operation

xe_mmio_rmw32 was failing to invert the passed in mask, resulting in a
register update that wasn't the expected RMW operation.  Fortunately the
impact of this mistake was limited, since this function isn't heavily
used in Xe right now; this will mostly fix some GuC PM interrupt
unmasking.

v2:
 - Rename parameters as 'clr' and 'set' to clarify semantics.  (Lucas)
