iio: adc: sun4i: add THERMAL dependency
With CONFIG_THERMAL=m and CONFIG_SUN4I_GPADC=y, we get a link error from calling devm_thermal_zone_of_sensor_register: drivers/iio/built-in.o: In function `sun4i_gpadc_probe': :(.text+0x1c284): undefined reference to `devm_thermal_zone_of_sensor_register' This adds a Kconfig dependency to ensure we can only have the ADC driver as built-in when this function is also built-in, or when we see the empty stub implementation. When the thermal code is a module, we can still build the adc driver as a module, too.

Say yes here to build support for Allwinner (A10, A13 and A31) SoCs
GPADC. This ADC provides 4 channels which can be used as an ADC or as
