[PATCH] arm64: dts: rockchip: Enable bluetooth of AP6611s on OPI5 Max/Ultra

[Jimmy Hon]

Orange Pi 5 Max and Ultra has onboard AP6611s with Bluetooth 5.3
connected via UART7.

The chip reports as:
[    3.747864] Bluetooth: hci0: BCM: chip id 3
[    3.750021] Bluetooth: hci0: BCM: features 0x0f
[    3.775923] Bluetooth: hci0: SYN43711A0
[    3.775930] Bluetooth: hci0: BCM (001.001.030) build 0000
