arm64: dts: rockchip: Fix compatible for Bluetooth on rk3566-anbernic
The realtek Bluetooth module uses the same driver as the realtek,rtl8822cs-bt and the realtek,rtl8723bs-bt, however by selecting the 8723bs advanced power saving features are disabled that appear to interfere with normal operation of the bluetooth module. This change switches the compatible string to disable power saving. Without this patch evtest of a paired bluetooth controller fails, with this patch the controller operates as expected.
