Instead there's now a dedicated thermal sensor. Disable the BL30 integration for G12A and newer SoCs to save a few CPU cycles when reading samples. Adding a separate struct meson_sar_adc_data is a good idea anyways because starting with G12A there's some extra registers to read the samples in a simplified way.
