We're fetching GuC/HuC firmwares directly from uc level during
init_early stage but this breaks guc/huc struct isolation and
also strict SW-only initialization rule for init_early. Move fw
fetching to init phase and do it separately per guc/huc struct.
v2: don't forget to move wopcm_init - Michele
v3: fetch in init_misc phase - Michal
