This new hook will allow targets to recognize an alignment
fault with the correct priority with respect to other faults
that can be raised by paging.
This should fix several hppa fault priority issues, most
importantly that access permissions come before alignment.
This should fix the documented error in the Arm alignment
fault due to memory type.
Changes for v3:
- Change the tlb_fill_hook to return data into provided
CPUTLBEntryFull, instead of calling tlb_set_page*.
- I have dropped some r-b, correspondingly.
