Fix addressing, zero-init, and compatibility bugs in a3fe378

- Including missing dereference to finish getting the address of
  the control register range
- Add zero-initialization to the proc_ops structure in copat_ops to
  insure that all intentionally unset fields remain unset
- Set .llseek in all the file_operations structures, as recent
  kernels require this to be explictly set
