Subject: [PATCH 1/1] riscv: Change memblock reserved name to be recognized on kexec

memblock resreved exposes as Reserved on iomem,
kexec tool doesn't take those parts to vmcore, but
the kernel use those address and it needed when opening the vmcore.
Without this fix the crash-tool fails.

Fixes: e94eb7ea6f20 ("riscv: Properly export reserved regions in /proc/iomem")
