Change in flashrom[master]: Add ability to read fmap from ROM

[David Hendricks (Code Review)]

Hello build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/27480

to look at the new patch set (#2).

Change subject: Add ability to read fmap from ROM
......................................................................

Add ability to read fmap from ROM

This adds logic to search the ROM for the flashmap.

It also changes the fmap-related CLI options so that --fmap will cause
flashrom to search the ROM for the fmap, while --fmap-file <filename>
will look in <filename>.
