arm64: dts: imx8mp libra: add peb-av-10 expansion board overlay

Browse Source 
Add an overlay of expansion board (PEB-AV-10) that supports multimedia
interfaces, 3.5mm headphone jack, a USB-A port and LVDS, backlight
connectors can be connected to the imx8mp libra. Audio works when no
display is connected to expansion board.

A separate overlay for Powertip display, based on peb-av-10.dtsi and
intended for use with PEB-AV-10 expansion board, will be added
later as display support is not yet available.
