arm64: dts: amlogic: meson-s4-s905y4-khadas-vim1s: enable bluetooth

The Khadas VIM1S board uses the Ampak AP6256 Wi-Fi/Bluetooth module.
The Bluetooth controller is connected via UART_A and requires the
external 32k clock (LPO).

Enable the UART_A node and add the bluetooth child node to support it.
