fsl-mc lazyapply command applies dpl from efi_exit_boot_services(). Status of fsl-mc node in working fdt is updated at this stage. However, an efi application like grub may already have copied the fdt. So the updates to fdt done at efi_exit_boot_services() may not be visible to the OS. Fix it by updating fdt earlier if fsl-mc lazyapply command is used.
