thermal: qpnp-adc: Update ADC_TM peripheral registration

Register ADC_TM peripheral with of_thermal to support
clients using thermal core to set trips and read temperature.
Update ADC_TM driver to activate the trip threshold for
warm and cool zones when thermal core sets the trip threshold
and enable the sensor.

In addition remove support for qpnp-adc-tm peripheral register
configuration.
