arm64: dts: ti: k3-am62-verdin: Add NAU8822 Bridge Tied Load
Add a device tree overlay enabling Bridge Tied Load (BTL) mode on the
Nuvoton NAU8822 audio codec present on the Verdin Development Board.
In BTL mode, the two loudspeaker outputs are bridged to deliver higher
output power on the X28 speaker connector.
