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
