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. Move fw fetching to
init phase and do it separately per guc/huc struct.

Can you resend this as a 2-patch series and with the "HAX enable guc,
huc for CI" as the second patch? We want some CI testing for this.
Also, won't this should also move intel_wopcm_init()?
We need the guc/huc fw size for the wopcm stuff.
