regulator: Specify REGULATOR_CHANGE_STATUS for WM835x LED constraints

The WM8350 LED driver needs to be able to enable and disable the
regulators it is using. Previously the core wasn't properly enforcing
status change constraints so the driver was able to function but this
has always been intended to be required.
