rambi: make ramids non-legacy gpio inputs
The romstage code for rambi uses the mmio way of reading
inputs. However, this is a problem is the GPIOs are set up
as legacy mode. Subsequent warm resets mean the ram_id is
read incorrectly. Ensure the ram_id is read consistently
by keeping the GPIOs for ram_id in mmio mode.
BUG=chrome-os-partner:24085
BRANCH=None
TEST=Built and booted. And rebooted. Now seeing consistent ram_id
values on warm resets.
