[PATCH v3 4/5] arm64: dts: allwinner: a523: Add UART1 pins

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens at csie.org>

UART1 is normally used to connect to the Bluetooth side of a Broadcom
WiFi+BT combo chip. The connection uses 4 pins.

Add pinmux nodes for UART1, one for the RX/TX pins, and one for the
RTS/CTS pins.
