Hudson: Changes to support agesa/hudson for legacy free
Add Kconfig option for Legacy free and hook it into the parmer AGESA initialization as well as the FADT code. This should really be done inside the southbridge wrapper and not in the mainboard, but for now the code to attach it to is inside the mainboard. Update Kconfig for parmer and thatcher to default to legacy free.
