Subject: [PATCH] Fix undefined references for fdt when building with platform
 emu

The fdt module isn't build for this platform, so adding the declarations
with platform emu will lead to the following undefined reference errors:

BUILDSTDERR: /usr/bin/ld: grub_emu_lite-symlist.o:(.data+0x500): undefined reference to `grub_fdt_add_subnode'
BUILDSTDERR: /usr/bin/ld: grub_emu_lite-symlist.o:(.data+0x518): undefined reference to `grub_fdt_check_header'
