Add a new compatible string "qcom,pmk8350-pon" for GEN3 PMIC PON
peripherals and update "reg" property.
Also, Add an optional "reg-names" property to differentiate between
GEN1/GEN2 and GEN3 peripherals. GEN1/GEN2 peripherals only need one
register address to be specified (e.g. "pon") whereas GEN3 peripherals
can have two register addresses specified ("hlos", "pbs").
