power: suppy: ucs1002: disable power when max current is 0

Browse source

For some devices userspace needs the ability to completely cut the power
to the USB devices connected to the charge controller. An easy way to
achieve this is by allowing 0 as a valid max current and forcibly disable
the output in that case, as well as enable it again if the regulator is
in use and a non-0 max current is set.
