Subject: [PATCH] ARM: dts: vf610-zii-dev: enable vf610 builtin temp sensor

Vybrid has single internal temperature sensor connected to both internal
ADC modules.

vf610-zii-dev already has ADC0 enabled. Now, to get temperature sensor
captured by iio_hwmon driver, need to configure iio_hwmon node to use
that ADC.
