[U-Boot] [PATCH 1/2] board: lx2160a: fix fsl-mc status in fdt with bootefi

[Mian Yousaf Kaukab]

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.
