arm64: dts: rockchip: fix quartz64-a bluetooth configuration

For "Quartz64 Model A" add missing RTS line to the UART interface used by
bluetooth and swap bluetooth host-wakeup and device-wakeup gpio pins to
match the boards physical layout. This changes are necessary to make
bluetooth provided by the wireless module work.

Also set max-speed on the bluetooth device as it's not automatically
detected.
