google/gru: Read RAM & board ids from the ADC

- Update so that the RAM id is read from ADC instead of
hard-coded from the config array.
- Update the boardid readings so that they are bucketed instead
of within an error margin.

BRANCH=None
BUG=chrome-os-partner:54566,chrome-os-partner:53988
TEST=hexdump /proc/device-tree/firmware/coreboot/ram-code
     and boardid when OS boots up.  Also verified that
     voltage read in debug output returns correct id.
