ARM: dts: omap4-embt2ws: Add Bluetooth

Since the required clock is now available, add bluetooth.

Note: Firmware (bts file) from device vendor reroutes tx for some time
during initialisation and later put it back, producing timeouts in
bluetooth initialisation but ignoring that command leads to proper
initialisation.
