Change in flashrom[master]: layout: Add -i <region>[:<file>] support.

[David Hendricks (Code Review)]

Hello Carl-Daniel Hailfinger, Arthur Heymans, Nicola Corna, Paul Menzel, build bot (Jenkins), Nico Huber,

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

https://review.coreboot.org/23021

to look at the new patch set (#11).

Change subject: layout: Add -i <region>[:<file>] support.
......................................................................

layout: Add -i <region>[:<file>] support.

Add an optional sub-parameter to the -i parameter to allow building the
image to be written from multiple files. This will also allow regions to
be read from flash and written to separate image files.

This is a rebase of a patch that was ported from chromiumos. A lot of
things have changed, but the idea is the same.

Original patch by Louis Yung-Chieh Lo :
Summary: Support -i partition:file feature for both read and write.
