hwmon: qpnp-adc-tm: Optimize and add more TM channel support
The change adds 3 additional channels and run-time
detects the supported number of channels to allow
clients to set threshold notification.
To support this, optimize the kernel api used to configure
and start a threshold monitoring request to include multiple
clients thus avoiding the need to have seperate kernel api's
for different clients. Changes are made to avoid the driver
depending on the order in which the VADC_TM DT channel
nodes should be added. Support is now included to
monitor DIE temperature for reading the pmic_therm, VBATT
and msm_thermistor scaling functions.
The change also disables the bank when an interrupt is
received or any changes are to be made in the settings,
make sure no measurements are in the queue, settings updated
and the bank is re-enabled.
