[PATCH v1 08/17] rockchip: adc: enable spl compile class driver

[Johan Jonker]

Enable spl compile of the class driver for other
compile modes then OF_REAL, so that at least it
doesn't break the process. Use #if because code
review shows that IS_ENABLED() and
device_get_supply_regulator() results in probe failure.
