imx8mm-mx8menlo/verdin-imx8mm: synchronise device tree with linux

Synchronise device tree with linux v5.19-rc5.

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 Verdin Development (carrier) board (e.g.
imx8mm-verdin-wifi-dev.dtb rather than the previous imx8mm-verdin.dtb).

Please further note that the PMIC node name got changed from a pmic
label to pmic@25 which required adjustment in resp. board SPL file
board/toradex/verdin-imx8mm/spl.c.
