drm/i915: Decouple GuC log setup from verbosity parameter
GuC Log buffer allocation was tied up with verbosity level module param
i915.guc_log_level. User would be given a provision to enable firmware
logging at runtime, through a host2guc action, and not necessarily during
Driver load time. But the address of log buffer can be passed only in
init params, at firmware load time, so GuC has to be reset and firmware
needs to be reloaded to pass the log buffer address at runtime.
To avoid reset of GuC & reload of firmware, allocation of log buffer will
be done always but logging would be enabled initially on GuC side based on
the value of module parameter guc_log_level.
v2: Update commit message to describe the constraint with allocation of
log buffer at runtime. (Tvrtko)
v3: Rebase.
