Subject: [PATCH v3] 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.

Fixes: b33a22a1e7c4248608e533fc4fa524258b3fae84 (arm64: dts: rockchip: add basic dts for Pine64 Quartz64-A)
