drm/xe/guc: Request max GT freq during resume

Browse Source 
We already request max freq in the load path, moving it
to __xe_guc_upload will ensure this speeds up GuC load in
the resume path as well.

v2: Rename xe_guc_pc_init_early since we now call it per
GuC load (Michal W)

v3: Keep pc_init_early() and init RPx values there (Rodrigo)
