[PATCH v1 27/33] iio/drivers/sun4i_gpadc: Switch to new of thermal API

[Daniel Lezcano]

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach.

Use this new API.

Why is the const removed? If the framework modifies the structure you 
need a per device copy of the struct.
