drm/i915/uc: Sanitize uC together with GEM
Instead of dancing around uC on reset/suspend/resume scenarios,
explicitly sanitize uC when we sanitize GEM to force uC reload
and start from known beginning.
v2: don't forget about reset path (Daniele)
sanitize uc before gem initiated full reset (Daniele)
v3: drop redundant disable_communication in init_hw (Daniele)
