soc/amd/common/psp_verstage: Fix build for FMAP without RW slots
On FMAP without RW slots, PSP verstage fails to build because of
reference to FMAP_SECTION_FW_MAIN_A_*. Instead extract the offset and
size of relevant sections using fmap_locate_area().
BUG=b:240664755
TEST=Build and boot to OS in Skyrim with unsigned PSP verstage.
