arm64: dts: mediatek: mt8183-kukui: Clean up IT6505 regulator supply

Align the name of the regulator with the design schematic. Also fix up
the gpio property to the new "gpios" property name, and add the
GPIO_ACTIVE_HIGH flag. The flag is actively ignored in Linux in favor of
the old "enable-active-high" property; nevertheless it is the correct
description.
