Add the ability to enable or disable multiple regulators in bulk with camss. This is useful for sm8250, sdm845 and it looks like sdm660 where we have more than one CSI regulator to do at once. It should just work for standalone existing vdda regulators and parts which don't have an explicitly defined CSI regulator.
