dm: adc: add Exynos54xx compatible ADC driver

This commit adds driver for Exynos54xx ADC subsystem.

The driver is implemented using driver model, amd provides
ADC uclass's methods for ADC single channel operations:
- adc_start_channel()
- adc_channel_data()
- adc_stop()

The basic parameters of ADC conversion, are:
- sample rate: 600KSPS
- output the data as average of 8 time conversion

ADC features:
- sample rate: 600KSPS
- resolution: 12-bit
- channels: 10 (analog multiplexer)
