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.
