soc/amd/stoneyridge|mb: Add Kconfig symbol for Prairie Falcon

The stoneyridge code inferred that if Merlin Falcon was built but no
Merlin Falcon binaries were present, the intent must be Prairie Falcon.
The two falcons are Embedded variants, and Prairie Falcon falls within
Family 15h Models 70h-7Fh.

Add a Prairie Falcon symbol that can be used explicitely.  Drop
HAVE_MERLINFALCON_BINARIES.
