drm/xe: Initialize GuC earlier during probe
SR-IOV VF has limited access to MMIO registers. Fortunately, it is able
to access a curated subset that is needed to initialize the driver by
communicating with SR-IOV PF using GuC CT.
Initialize GuC earlier in order to keep the unified probe ordering
between VF and PF modes.
