Mian Yousaf Kaukab 7e96804975 fsl-layerscape: dpaa: fix fsl-mc status in fdt with bootefi
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.

Fixes: b7b8410a8f (ls2080: Exit dpaa only right before exiting U-Boot)
