Update the description of "reg" property to add the PON_PBS base
address along with PON_HLOS base address.  Also add "reg-names"
property description.

You miss here min and maxItems

Skip description. You miss here min and maxItems.

No clue why you made three if statements. This is one if for all three
variants.

Sorry about that was not sure how to combine the if statements originally.
Found that you could do:

- if:
      properties:
        compatible:
          contains:
            enum:
              - qcom,pm8916-pon
              - qcom,pms405-pon
              - qcom,pm8998-pon
    then:
     ...

I was wondering if for the "qcom,pmk8350-pon" compatible would you rather
have the if statement the way it is or have it follow the same pattern as
above i.e.

contains:
  const: qcom,pmk8350-pon

vs

contains:
  enum:
    - qcom,pmk8350-pon

The former. If only 1 possibility, use 'const'.
