imx6q-lxr: Add board support

Add support for the Comvetia i.MX6Q LXR2 board, which is
uses the Phytec PFLA02 SoM.

Based on the original work from Stefano Babic <sbabic@denx.de>.

The Phytec PFLA02 devicetrees are taken from kernel 6.11-rc7.

The imx6q-lxr.dts has been submitted upstream:

https://lore.kernel.org/linux-devicetree/20240913200906.1753458-3-festevam@gmail.com/

After it gets accepted in mainline (most likely in kernel 6.13),
the lxr2 board can then be switched to OF_UPSTREAM and these device trees
can be removed from U-Boot.
