From: ChiYuan Huang <cy_huang@richtek.com>

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 v3:
- Use a 'dev' variable and dev_err_probe to decrease the LOC in mfd.
- Simplify the power key irq handler key report
- Since press and release irq not needed to keep in private data, change 'press',
'release' irq as local variable only.
- Fix Kconfig typo for pwrkey.

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.
