include/fmap.h: Require FMAP_SECTION_FLASH_START == 0

For simplicity we are going to impose this restriction to coreboot.
Note however that this is only a restriction for coreboot itself. The
FMAP tool itself is still a generic tool that does not require the FMAP
to start at offset 0.

Add an defacto empty fmap_config.h to our test cases, since fmap.h now
includes fmap_config.h.
