drm/xe/migrate: Handle clear ccs logic for xe2 dgfx

Browse source

For Xe2 dGPU, we clear the bo by modifying the VRAM using an
uncompressed pat index which then indirectly updates the
compression status as uncompressed i.e zeroed CCS.
So xe_migrate_clear() should be updated for BMG to not
emit CCS surf copy commands.

v2: Moved xe_device_needs_ccs_emit() to xe_migrate.c and changed
name to xe_migrate_needs_ccs_emit() since its very specific to
migration.(Matt)
