This patch fixes the following dtbs_check errors:
1. 'mt6359rtc' do not match any of the regexes: 'pinctrl-[0-9]+'
- Update 'mt6359rtc' in 'mt6359.dtsi' with a generic device name 'rtc'
2. 'pmic: regulators: 'compatible' is a required property'
- Add 'mediatek,mt6359-regulator' to compatible property.
