[PATCH v2] drm/xe/uc: Apply RCS/CCS yield policy to SR-IOV VFs

[Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com>]

VFs were missing the call to apply the global scheduling policy.
Call xe_guc_submit_enable() during vf_uc_load_hw() to ensure VFs
get the same policy enforcement as PF.

Fixes: 26caeae9fb48 ("drm/xe/guc: Set RCS/CCS yield policy")

v2: Keep VF init order aligned with PF: call xe_guc_submit_enable() after
    xe_guc_opt_in_features_enable(). (Daniele)
