Eric Snowberg bc220962e3 ieee1275: prevent buffer over-read 
Prevent buffer over-read in grub_machine_mmap_iterate. This was
causing phys_base from being calculated properly. This then
caused the wrong value to be placed in ramdisk_image within
struct linux_hdrs. Which prevented the ramdisk from loading on
boot.

Newer SPARC systems contain more than 8 available memory entries.

For example on a T5-8 with 2TB of memory, the memory layout could
look like this:

Eric Snowberg 080a20861c OBP available region contains grub. Start at grub_phys_end. 
This prevents a problem where grub was being overwritten since
grub_phys_start does not start at a zero offset within the memory
map.
