RISC-V: load initrd wherever it fits into memory
[ Upstream commit c79e89ecaa246c880292ba68cbe08c9c30db77e3 ] Requiring that initrd is loaded below RAM start + 256 MiB led to failure to boot SUSE Linux with GRUB on QEMU, cf. https://lists.gnu.org/archive/html/grub-devel/2021-06/msg00037.html Remove the constraint.
