PATCH v3
1. fix Subject format
2. using correct patches version
3. remove '|'
4. remove allOf: &ref regulator.yaml#
5. remove redundant description
6. move BASE to base property with correct indentation
7. only using lowercase node name
8. make DT_CHECKER_FLAG=-m DT_SCHEMA_FILES=richtek,rt5133.yaml dt_binding_check pass

+description:
+ RT5133 is an integrated chip. It includes 8 LDOs and 3 GPOs that can be
+ used to drive output high/low purpose. The dependency of the GPO block
+ is internally LDO1 Voltage. If LDO1 voltage output disabled, GPO cannot
+ be used to drive output high. It need to pay more attention on the usage.
