soc/amd/common: Allow AGESA file split for pre- and post-memory
By splitting the binary files for platform initialization, the
post-memory code can be modified to stop executing in place (--xip).
This change creates two separate sections in CBFS for AGESA and loads
the appropriate file at the correct stage.
BUG=b:68141063
TEST=Booted kahlee with split agesa enabled.
