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.
