H A Dgpio.he5901c94 Mon Nov 10 19:00:21 CST 2014 Simon Glass <sjg@chromium.org> dm: gpio: Add a function to read an ID from a list of GPIOs

For board IDs a common approach is to set aside several GPIOs for use in
determining the board ID. This can provide information about board features
and the revision.

Add a function that turns a list of GPIOs into an integer by assigning
each GPIO to a single bit.
