Detail:
* Use the new OS_Memory 23 memory reservation system to stop other DAs
claiming exclusive use of the physical memory we want to use for the PCI
heap
* Switch to using the new OS_Heap 8 instead of OS_Heap 7, so that memory
alignment can be handled in terms of physical address insead of logical
address (avoiding the need to ensure the DA is both logically and
physically aligned)
* Make sure the DA max size matches the amount of memory we found, so
that if we can't get the full 32MB as desired, we don't run the risk of
growing the DA into a non physically contiguous chunk of RAM
