Add basic FMAP to EC firmware image.
This is very basic, so you can only rely on RO_SECTION, RW_SECTION_A, and
RW_SECTION_B for now. We'll fill in more regions as we add vboot stuff.
Still, you should be able to do things like this:
flashrom -p internal:bus=lpc -r ec.bin
flashrom -p internal:bus=lpc -w ec.bin -i RW_SECTION:ec.B.flat
BUG=chrome-os-partner:8198
TEST=manual
Build the image, look for the FMAP in it.
cd src/platform/ec
make BOARD=link
dump_fmap ./build/link/ec.bin
