    mainboard/google/reef: Add PowerResource for ELAN touchscreen
    
    Define reset_gpio and enable_gpio for touchscreen device so that when
    kernel puts this device into D3, we put the device into
    reset. PowerResource _ON and _OFF routines are used to put the device
    into D0 and D3 states.
