efi_loader: Call fdt preparation functions
We have a nice framework around image fils to prepare a device tree
for OS execution. That one patches in missing device tree nodes and
fixes up the memory range bits.
We need to call that one from the EFI boot path too to get all those
nice fixups. This patch adds the call.
