Subject: [PATCH] Fix build error with the fdt module on risc-v

The risc-v architecture also uses Device Trees, but the symbols in the
fdt header aren't defined for this arch which lead to following error:

BUILDSTDERR: ../../grub-core/loader/efi/fdt.c: In function 'grub_fdt_load':
BUILDSTDERR: ../../grub-core/loader/efi/fdt.c:48:39: warning: implicit declaration of function 'grub_fdt_get_totalsize' [-Wimplicit-function-declaration]
BUILDSTDERR:    48 |       size = GRUB_EFI_BYTES_TO_PAGES (grub_fdt_get_totalsize (fdt));
