[PATCH v4 3/3] arm64: dts: allwinner: a64: Enable Bluetooth on Teres-I

[Hugo Grostabussiat <bonstra@xxxxxxxxxxxxxxxxx>]

The UART1 on the Teres-A64-I is connected to a rtl8723bs combo
WLAN/Bluetooth controller, with three GPIOs used for device reset,
host wake up and device wake up.

Currently, the host wake up feature is not supported by the HCI H5
driver.
