drm/i915/guc: Make the GuC fw loading helper functions general

Browse Source 
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/INTEL_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: removed G from messages in shared fw fetch function.
v4: rebased.Updated dev to dev_priv in intel_guc_setup(), guc_fw_getch()
and intel_guc_init().
v5: rebased. Remove uint32_t fw_type to patch 2. Add INTEL_ prefix for
fields in enum intel_uc_fw_status. Remove uc_dev field since its never
used.Rename uc_fw to just fw and guc_fw to fw to avoid redundency.
v6: rebased. Remove sections of code that were commented and no longer
required.
v7: rebased. Remove uc_fw_ prefix from path and obj fields
in intel_uc_fw struct as suggested by Michal.
v8: rebased. Add declaration of intel_guc_wopcm_size() in
this patch instead of patch 3.
