soc/amd/picasso: use output of fmaptool to find APOB region
Parse the generated fmap_config.h file instead of the .fmd file supplied
by the board to determine the size and location of the APOB region.
Parsing the generated file allows to write .fmd files without having to
take into account that the shell script part in Picasso's Makefile.inc
can only parse a subset of the .fmd syntax.
BUG=b:157068645
TEST=Timeless build for amd/mandolin resulted in identical binary.
BRANCH=zork
