ARM: dts: imx7d-pico: describe Bluetooth controller

Browse Source 
Ampak AP6335i Wi-Fi module atop i.MX7D Pico SoM also supports Bluetooth 4.1
via UART attached to "serial6" port. Describe it, so the controller can
probe automatically on boot.

This is based on "Pico i.MMX Development Kit for Android Things Hardware
Manual" rev. B1 [1], Table 6 on page 12.
