drm/xe/wa: Apply tile workarounds at probe/resume
Although the vast majority of workarounds the driver needs to implement
are either GT-based or display-based, there are occasionally workarounds
that reside outside those parts of the hardware (i.e., in they target
registers in the sgunit/soc); we can consider these to be "tile"
workarounds since there will be instance of these registers per tile.
The registers in question should only lose their values during a
function-level reset, so they only need to be applied during probe and
resume; the registers will not be affected by GT/engine resets.
Tile workarounds are rare (there's only one, 22010954014, that's
relevant to Xe at the moment) so it's probably not worth updating the
xe_rtp design to handle tile-level workarounds yet, although we may want
to consider that in the future if/when more of these show up on future
platforms.
