sb/amd/pi/hudson/Kconfig: replace HUDSON_LEGACY_FREE option 

HUDSON_LEGACY_FREE controlled both if the legacy devices and the 8042
flags are set in the IA-PC boot architecture filed of the FADT. Since
some systems have legacy devices on the LPC bus, but no 8042-compatible
keyboard controller, replace this option with the two new options
HUDSON_FADT_LEGACY_DEVICES and HUDSON_FADT_8042.

TEST=The FACP table doesn't change on APU2
