drm/i915/guc: Extract param logic form guc_init_fw()
Let intel_guc_init_fw() focus on determining and fetching the correct
firmware.
This patch introduces intel_uc_sanitize_options() that is called from
intel_sanitize_options().
Then, if we have GuC, we can call intel_guc_init_fw() conditionally
and we do not have to do the internal checks.
v2: fix comment, notify when nuking GuC explicitly enabled (M. Wajdeczko)
v3: fix comment again, change the nuke message (M. Wajdeczko)
v4: update title to reflect new function name + rebase
v5: text && remove 2 uneccessary checks (M. Wajdeczko)
