x86: Add support for m5ops through a memory mapped interface
In order to support m5ops in virtualized environments, we need to use a memory mapped interface. This changeset adds support for that by reserving 0xFFFF0000-0xFFFFFFFF and mapping those to the generic IPR interface for m5ops. The mapping is done in the X86ISA::TLB::finalizePhysical() which means that it just works for all of the CPU models, including virtualized ones.
