AGESA: Introduce AGESA_LEGACY and its counterpart

We define AGESA_LEGACY as an implementation of mainboard
that has its romstage main completely under mainboard/
directory. We have learnt from other platforms this approach
has several downsides when it comes to making platform-wide

We start by creating per-family romstage.c file, which
boards will gradually take into use by removing the
AGESA_LEGACY Kconfig option we here apply to all of them.
