[PATCH 1/6] drm/i915/guc: Make the GuC fw loading helper functions general

[yu.dai@intel.com]

From: Alex Dai <yu.dai@intel.com>

Rename some of the GuC fw loading code to make them more general. We
will utilize them for HuC loading as well.
    s/intel_guc_fw/intel_uc_fw/g
    s/GUC_FIRMWARE/UC_FIRMWARE/g

Struct intel_guc_fw is renamed to intel_uc_fw. Prefix of tts members,
such as 'guc' or 'guc_fw' either is renamed to 'uc' or removed for
same purpose.
