mb/google/brya/var/glassway: Add Stylus Function
1. Add STYLUS fw_config setting. 2. Enable stylus device settings. 3. Disable the stylus GPIO pins based on fw_config. BUG=b:364798563 BRANCH=firmware-nissa-15217.B TEST=1. emerge-nissa coreboot 2. Confirm command evtest for stylus PRP0001:00 and workable.
