This function should take the same arguments as bus_space_mmap(9).  I've
added "int prot" and "int flags":

        void *bus_space_physload(bus_space_tag_t space, bus_addr_t addr,
            bus_size_t size, int prot, int flags);

"int prot" is the device's characteristic.  Audio mic devices would use
VM_PROT_READ.  Framebuffers would use VM_PROT_WRITE.  We need to introduce
BUS_SPACE_PROT_* symbols too.
