Staging: comedi: Kconfig dependancy fixes

There are three minor changes I would like to do on my last patch:

* Comedi is formally not dependant on any hardware, e.g. it is possible
  to use comedi_test without (PCI || PCMCIA || PCCARD || USB || ISA)
* comedi_parport is not dependant on PARPORT_PC.
* indirect ni_mio_cs (16-bit PCMCIA) dependancy on mite PCI-chip may
  confuse users, thus changing COMEDI_NI_TIO depends on COMEDI_MITE
  to select COMEDI_MITE.
