Implements the on-chip flash erasing and writing functions. The actual writing is done from a routine in internal RAM (using the special .iram.text section) with interrupt disabled as we cannot read flash during the writing process. The write-protect feature is only lightly tested. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BUG=chrome-os-partner:8865 TEST=run on Daisy, from the EC console, use flasherase and flashwrite commands and observe the results using rw command.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
