mb/google/sarien/variants/sarien: Using HID over I2C to enable Melf TouchScreen

Current Melfas touchscreen driver cannot unregister ifself when
connecting without Melfas touchscreen or connecting with other devices.
And Melfas touchscreen FW can use I2C and HID over I2C driver, so
switch to using HID over I2C driver.

BUG=b:122710830
BRANCH=master
TEST=Verify touchscreen on sarien works with this change.
