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.
