From: Samuel Holland <samuel@sholland.org> The Orange Pi Win exposes several UARTs on header pin, and connects one to the on-board WiFi/Bluetooth chip. Add the pinmux definitions to the UART nodes, but keep them disabled.

What BT chip is there? Does it have serdev support? If so, that should be enabled here.
