drm/i915/guc: Move defines with size of GuC logs to intel_guc_log.h

Browse Source 
At this moment, we have defined GuC logs sizes in intel_guc_fwif.h, but
as these values are related directly to the GuC logs, and not to API of
GuC parameters, we should move these defines to intel_guc_log.h.

v2:
- change buffers size to more friendly (Michał Wajdeczko)
- remove GUC_LOG_SIZE define (Michał Wajdeczko)
v3:
- use SZ_* macros to define buffers sizes (Michał Wajdeczko)
