[ 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.
