[PATCH 1/8] drm/i915/guc: Make the GuC fw loading helper functions general

[Anusha Srivatsa <anusha.srivatsa@intel.com>]

From: Peter Antoine <peter.antoine@intel.com>

Rename some of the GuC fw loading code to make them more general. We
will utilise 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.

v2: rebased on top of nightly.
    reapplied the search/replace as upstream code as changed.
v3: rebased again on drm-nightly.
v4: removed G from messages in shared fw fetch function.
v5: rebased.
v7: rebased.
v8: rebased.
v9: rebased.
v10: rebased.
v11: rebased.
v12: rebased on top of drm-tip
