dt-bindings: iio: adc: Add rockchip,rk3528-saradc variant

Browse Source 
The Successive Approximation ADC (SARADC) in RK3528 uses the v2
controller and support:
- 10-bit resolution
- Up to 1MS/s sampling rate
- 4 single-ended input channels
- Current consumption: 0.5mA @ 1MS/s

Add a rockchip,rk3562-saradc compatible string for the 4 channels of
10-bit resolution supported by SARADC in RK3528.
