Subject: [PATCH v3 09/30] iio: adc: Threat A33 as thermal sensor and remove non thermal sun4i channel

We want to use this driver mostly as thermal sensor, that still supports
the adc for the older chips, thus we threat the A33 as thermal sensor.
We also remove the adc channel without thermal support.
