soc/amd: factor out legacy I/O and cf9 decode enable functions
Replace sb prefix with fch prefix, since those are all FCHs and no south
bridges any more. Verstage on PSP uses the I/O access mechanism instead
of the MMIO one, so keep a separate function for that, but also move it
to the common mmio_util file to have them all in one place.
