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. imx8mp-verdin-wifi-dev.dtb rather than the previous imx8mp-verdin.dtb).
