acpigen: Add stop gpio control to power resource

There is at least one I2C device (being used by Soraka) that has 3
controls -- enable, reset and stop. If the stop gpio is not put into
the right state when turning off the device in suspend mode, then it
causes leakage. Thus, we need control in power resource to be able to
stop the device when entering suspend state.

TEST=Verified on soraka that touchscreen stop is correctly configured
on suspend.
