PATCH v3 2/2 regulator: rt6160: Add support for Richtek RT6160

From: ChiYuan Huang <[email protected]>

Add support for Richtek RT6160 voltage regulator. It can provide up to 3A output current within the adjustable voltage from 2025mV to 5200mV. It integrate a buckboost converter to support wide input voltage range from 2200mV to 5500mV.

---
since v3
- Use more header file like as of_regulator.h and property.h.
- Change the parsing string from 'richtek,vsel_active_low' to 'richtek,vsel-active-low'.
- Use of_get_regulator_init_data to get the regulator init_data.

since v2
- Fix W=1 warning for of_device_id.
