drm/xe/pcode: Treat pcode as per-tile rather than per-GT
There's only one instance of the pcode per tile, and for GT-related
accesses both the primary and media GT share the same register
interface. Since Xe was using per-GT locking, the pcode mutex wasn't
actually protecting everything that it should since concurrent accesses
related to a tile's primary GT and media GT were possible.
