pseries: Add real mode debugging hcalls
PAPR systems support several hypercalls intended for use in real mode debugging tools. These implement reads and writes to arbitrary guest physical addresses. This is useful for real mode software because it allows access to IO addresses and memory outside the RMA without going through the somewhat involved process of setting up the hash page table and enabling translation. We want these so that when we add real IO devices, the SLOF firmware can boot from them without having to enter virtual mode.
