mem_region: Add HW-only memory resevations
Add a new type of memory reservation that indicates a memory region is
only used by hardware and should not be touched by software. This is
needed for the in-memory tracing buffers. These reservations have the
"no-map" property which indicates that the host kernel should not setup
any virtual address mappings that cover this range, unless of course a
device driver does so explicitly.
