x86/microcode/AMD: Rename a couple of functions

Browse Source 
- Rename apply_microcode_early_amd() to early_apply_microcode():
simplify the name so that it is clear what it does and when does it do
it.

- Rename __load_ucode_amd() to find_blobs_in_containers(): the new name
actually explains what it does.

Document some.

No functional changes.
