[PATCH v2 0/4] Add Richtek RT5120 PMIC support

[cy_huang]

From: ChiYuan Huang <cy_huang@xxxxxxxxxxx>

This patch series is to add Richtek RT5120 PMIC support.
In RT5120, it integrates four channels of buck converter, one channel of LDO,
and one external enable channel to control the external power source.

Since v2:
- Add 'unevaluatedProperties: false' for regulator buck1~4/ldo/exten.
- Fix indention and remove status for powerkey.
- Refine powerkey description for more HW details.
- For the regulator property parsing, use of_property_read_u32 instead.
- Not to overwrite regulator constraint.
- Refine regulator desc coding.
