Subject: Add blocksize functions to physical memory.  Fix the port we were
 using in the process loader.

mem/physical.cc:
    Implement the blockSize function, return VMPageSize for the physical memory
mem/port.hh:
    Add a function to get a pointer to a peer, needed for initVirtMem to work in the loader.
sim/process.cc:
    The way the translating port is setup we don't want the memory port, we want the peer port associated with that memory.  We may need to revisit this.
