From: Sagar Arun Kamble <sagar.a.kamble@xxxxxxxxx>
GuC Log buffer allocation was tied up with verbosity level kernel parameter
i915.guc_log_level. User could be given a provision to enable logging at
runtime and not necessarily during load time only. This patch will perform
allocation of shared log buffer always but will initially enable logging on
GuC side through init params based on i915.guc_log_level.
