power: supply: rt9467: Make charger-enable control as logic level
[ Upstream commit 5d80a86a99d524b0d89ff3906c6200b9f57b66f8 ]
The current coding make 'charger-enable-gpio' control as real hardware
level. This conflicts with the default binding example. For driver
behavior, no need to use real hardware level, just logic level is
enough. This change can make this flexibility keep in dts gpio active
level about this pin.
