drm/xe: Move xe_gt_init_early() where it belongs

Early shall be early enough, stop doing other things with gt before it.
Now that xe_gt_init_early() doesn't need forcewake and doesn't depend on
the fake engine_mask initialization, move it where it belongs: it
doesn't need to be after hwconfig config anymore.
