Split out SFC logic and add support for AST2400

Refactored the PNOR device driver to pull all SFC-specific
code into a new set of classes.  Any time a new type of
serial flash controller (SFC) is introduced, a new subclass
should be created to support it.
Also added the full support for the AST2400 BMC that is
being used on Palmetto.
