staging: comedi: 8255_pci: move ni_pcidio 8255 board support 

The 8255 based boards in the ni_pcidio driver are all simple
memory mapped 8255 boards that don't require the dma support
provided by the mite driver.

Move the support for these boards from the ni_pcidio driver to
the generic 8255_pci driver.

The DIO-96 appears as four 8255 subdevices. See the 8255
driver notes for details.
The DIO32HS board appears as one subdevice, with 32 channels.
Each channel is individually I/O configurable. The channel order
is 0=A0, 1=A1, 2=A2, ... 8=B0, 16=C0, 24=D0. The driver only
