AGESA,binaryPI: Move PORT80 selection to C bootblock

Because the function is implemented in C, post_code() calls
from cache_as_ram.S and other early assembly entry files may
not currently work for cold boots. Assembly implementation
needs to follow one day.

This effectively removes PORT80 routing from boards with
ROMCC_BOOTBLOCK.
