Re: [U-Boot] [U-Boot, v2, 2/6] dm: adc: uclass: get reference regulator once

device_get_supply_regulator() only needs to be called once. But each time there's call to adc_vxx_value() for instance, it calls adc_vxx_platdata_update() -> device_get_supply_regulator().

So, move device_get_supply_regulator() to pre_probe() routine.

This also allows vdd_supply/vss_supply to be provided directly from uc_pdata, e.g dt-binding variant like stm32-adc provide its own 'vref-supply'.

Applied to u-boot/master, thanks!
