charge_manager: allow finding supply with VOLT > 0 and CUR = 0
On Fizz if we boot from type-C and later on plug the BJ,
the BJ available current is set to a non-zero value but the current
is set to 0. Because of this it is impossible to detect at runtime
by the kernel that the BJ has been plugged in.
This commit is allowing to find power supply information even when
the current is equal to 0 as long as the voltage is > 0. The priority
will still be lower than if PWR > 0.
BUG=chromium:841944
BRANCH=none
TEST=Checked that the kernel can see when the BJ is connected.
