mb/google/nissa/var/yavilla: Add elan and G2 i2c touchscreen
Implement support for elan i2c touchscreen and use fw_config to pick between i2c or HID-over-i2c touchscreen. Support G2 TS have different slave address by fw_config BUG=b:295272539 BRANCH=firmware-nissa-15217.B TEST=build and verified touchscreen work Change-Id: I5e3f85106606d84e1cfa204e62b7b2662db6546b Signed-off-by: Shon Wang <shon.wang@quanta.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/77996 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Derek Huang <derekhuang@google.com>
