[OpenBIOS] [PATCH 1/3] SPARC32: fixup available memory list and modify ofmem_arch_get_virt_top()

[Mark Cave-Ayland]

In preparation for applying the ofmem_arch_get_virt_top() restriction to the
virtual memory region, fix up the calculation of the available list tail plus
increase the virtual memory region to cover the IO memory.
