soc/amd/common/vboot: Split transfer buffer methods into separate file

Browse Source 
I want to reuse the transfer buffer methods in SMM, so I need to add
them into their own file. I renamed `setup_cbmem_console` to
`replay_transfer_buffer_cbmemc` so it has a more descriptive name. I
also fixed the comment on `verify_psp_transfer_buf`.
