drm/xe: Invert mask and val in xe_mmio_wait32.

The order: 'offset, mask, val'; is more common in other
drivers and in special in i915, where any dev could copy
a sequence and end up with unexpected behavior.

Done with coccinelle:
@rule1@
expression gt, reg, val, mask, timeout, out, atomic;
@@
- xe_mmio_wait32(gt, reg, val, mask, timeout, out, atomic)
+ xe_mmio_wait32(gt, reg, mask, val, timeout, out, atomic)

spatch -sp_file mmio.cocci *.c *.h compat-i915-headers/intel_uncore.h \
       --in-place

v2: Rebased after changes on xe_guc_mcr usage of xe_mmio_wait32.
