This patch is moving guc_enable_communication and
guc_disable_communication to intel_guc.c and making it available for
use through intel_guc.h.
Intent is to reuse this function for calling from intel_uc_init_hw
and also as part of intel_uc_fini_hw where it will be coupled with
other teardown related to GuC in the upcoming patch.

Hmm, but both intel_uc_init_hw() and intel_uc_fini_hw() shall stay in
intel_uc.c and the best place for guc_[enable|disable]_communication()
functions is also in intel_uc.c as they provide generic switch between
MMIO/CT send mechanism, so I'm not so sure that we need this patch.
