Subject: [PATCH v5 12/13] arm64: allwinner: a64: add UART1 pin nodes

From: Andre Przywara <andre.przywara@....com>

On many boards UART1 connects to a Bluetooth chip, so add the pinctrl
nodes for the only pins providing access to that UART. That includes
those pins for hardware flow control (RTS/CTS).
