arm64: dts: freescale: imx8mm-verdin: Add NAU8822 Bridge Tied Load

Browse Source 
Add a device tree overlay for configuring the NAU8822 loudspeaker
outputs as a Bridge Tied Load (BTL) output on the Verdin Development
Board.

The overlay adds the codec property for the BTL-capable output
configuration, where the two loudspeaker outputs are combined for higher
output power.
