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.
