Instead of calling intel_guc_init() and intel_huc_init() one by one this
patch introduces intel_uc_init_fw() function that calls them both.
Called functions are renamed accordingly.
Trying to have subject_verb_object ordering and more descriptive names,
the intel_huc_init() and intel_guc_init() functions are renamed.
For guc_init():
* `intel_guc` is the subject, so those functions now take intel_guc
structure, instead of the dev_priv
* init is the verb
* fw is the object which better describes the function's role
huc_init() change follows the same reasoning.
v2: settle on intel_uc_fetch_fw name (M. Wajdeczko)
v3: yet another rename - intel_uc_init_fw (J. Lahtinen)
