    arm64: dts: mediatek: mt8183-kukui: Drop bogus output-enable property
    
    [ Upstream commit e9a9055fdcdc1e5a27cef118c5b4f09cdd2fa28e ]
    
    The "output-enable" property is set on uart1's RTS pin. This is bogus
    because the hardware does not actually have a controllable output
    buffer. Secondly, the implementation incorrectly treats this property
    as a request to switch the pin to GPIO output. This does not fit the
    intended semantic of "output-enable" and it does not have any affect
    either because the pin is muxed to the UART function, not the GPIO
    function.
    
    Drop the property.
