drm/xe/xe3p: Drop Wa_16028780921

Wa_16028780921 involves writing to a register that is locked by firmware
prior to driver loading and doesn't have any effect if implemented by
the KMD.  Since the implementation of the workaround actually belongs
the firmware, just drop the ineffective implementation by the KMD.
