mem: Refactor port proxies to support secure accesses

The current physical port proxy doesn't know how to tag memory
accesses as secure. Refactor the class slightly to create a set of
methods (readBlobPhys, writeBlobPhys, memsetBlobPhys) that always
access physical memory and take a set of Request::Flags as an
argument. The new port proxy, SecurePortProxy, uses this interface to
issue secure physical accesses.
