apalis_imx6: synchronise device tree with linux

Synchronise device tree with linux-next 20220706.

Please note that this also means that instead of the previous "generic"
U-Boot specific carrier board agnostic device tree we are now using the
regular one for the Apalis Evaluation (carrier) board (e.g.
imx6q-apalis-eval.dtb rather than the previous imx6-apalis.dtb).
