David Wu ae3ed042ed dm: adc: Add driver for Rockchip SARADC
The ADC can support some channels signal-ended some bits Successive Approximation
Register (SAR) A/D Converter, like 6-channel and 10-bit. It converts the analog
input signal into some bits binary digital codes.

config ADC
bool "Enable ADC drivers using Driver Model"
help
This enables ADC API for drivers, which allows driving ADC features
by single and multi-channel methods for:
- start/stop/get data for conversion of a single-channel selected by
a number or multi-channels selected by a bitmask
- get data mask (ADC resolution)
ADC reference Voltage supply options:
- methods for get Vdd/Vss reference Voltage values with polarity
- support supply's phandle with auto-enable
- supply polarity setting in fdt
