Default to using GRUB_MM_ADD_REGION_IN_RANGE on risc-v. This
is because the current grub risc-v ELF loader does not support
some of the relocations produced by -mcmodel=large (e.g. when
compiled with -mcmodel=large grub-mkimage returns 'error:
relocation 0x2b is not implemented yet.'), so it has to be
compiled with -mcmodel=medany, which only works if the grub code
fits in 2GiB.
