arm64: dts: mediatek: mt8183-kukui: Drop bogus output-enable property

Browse Source 
[ Upstream commit e9a9055fdc ]

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.
