[PATCH 12/15] drm/i915/guc: Remove i915_guc_log_unregister

[Sagar Arun Kamble]

Functionality needed to disable GuC interrupts and cleanup the
runtime/relay data structures is already covered in the unload path
via intel_guc_fini_hw and intel_guc_cleanup hence remove
i915_guc_log_unregister

v2: Removed the function i915_guc_log_unregister.

v3: Rebase as intel_guc.h is removed.
