drm/i915/guc: A little bit more of doorbell sanitization
Some recent refactoring patches have left the doorbell creation outside the GuC client allocation, which does not make a lot of sense (a client without a doorbell is something useless). Move it back there, and refactor the init_doorbell_hw consequently. Thanks to this, we can do some other improvements, like hoisting the check for GuC submission enabled out of the enable function. v2: Rebased.
