Now that the comedi_device has a 'mmio' and a 'iobase' member, this module can detect if the (*io) operations need to use readb/writeb for memory mapped I/O or inb/outb for port I/O. This can be use to cleanup a lot of the code duplication in the drivers that use the 8255 module. 1) Modify a couple comedi drivers that use port I/O for the 8255 device so that the 'iobase' is used for the base address of the 8255 device. 2) Add a comedi_device parameter to the (*io) callback. Tidy up the private (*io) callbacks to use this parameter. 3) Modify the default (*io) callback to use the comedi_device 'iobase'. Remove the, now redundant, dev->iobase from the 'iobase' that is passed to subdev_8255_init() for all callers that use the default (*io) callback. 4) Modify the default (*io) callback to use the comedi_device 'mmio'. Remove the private (*io) callbacks that use readb/writeb to access the hardware. 5) Modify the amplc_dio200_common module to use the 8255 module and remove the code duplication.
