sparc64 add mem to iomem resource

This patch adds sparc System RAM to /proc/iomem. By doing so, we also
restrict /dev/mem access to only known sparc RAM information obtained
from OBP during paging_init. Failing to restrict /dev/mem access can
lead to catastrophic issues with root access of /dev/mem - power off.
