drm/xe: check pcode init status only on root gt of root tile
The root tile indicates the pcode initialization is complete when all tiles have completed their initialization. So the mailbox can be polled only on the root tile. Check pcode init status only on root tile and move it to device probe early as root tile is initialized there. Also make similar changes in resume paths. v2: add lock/unlocked version of pcode_mailbox_rw to allow pcode init to be called in device early probe (Rodrigo) v3: add code description about using root tile change function names to xe_pcode_probe_early and xe_pcode_init (Rodrigo) Signed-off-by:Riana Tauro <riana.tauro@intel.com> Reviewed-by:
