After GPU reset, GuC HW needs to be reinitialized (with FW reload).
Unfortunately, we're doing some extra work there (mostly allocating stuff),
work that can be moved to guc_init and called once at driver load time.
As a side effect we're no longer hitting an assert in
i915_ggtt_enable_guc on suspend/resume.
v2: Do not duplicate disable_communication / reset_guc_interrupts
v3: Add proper teardown after rebase
