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.

Add device tree overlays for the Toradex OV5640 CSI Cameras on Verdin
AM62P CSI_1. Two variants are supported: the current CSI Camera Set 5MP
OV5640 with a 27 MHz oscillator and the legacy CSI Camera Module 5MP
OV5640 with a 24 MHz oscillator.
