CHROMIUM: Clean up cros gpio code
This CL simplifies how cros gpios are handled by moving the required logic out
of cros_gpio.c and into the application logic. This means that cros_gpio.c
assumes that none of the gpios are required, and just returns an error when
fetch is called. It's up to the caller of fetch to determine whether or not they
should ignore the error or act upon it.
BUG=chromium-os:21700
TEST=Tested on asymptote, ensured gpio access worked as expected.
