[PATCH] staging/comedi: Kconfig dependancy fixes

[Alexander Kurz]

There are tree minor changes I would like to do on my last patch:
> Subject: [PATCH] staging/comedi: new Kconfig and Makefiles, drivers grouped by bustype.

* 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.

thanks, Alexander
