Simon Glass e5901c94e3 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.
