staging: comedi: dmm32at: use 8255 module for Digital I/O subdevice The Dimond-MM-32-AT board uses an internal 82C55-type digital I/O circuit to provide the 24 digital I/O lines. The only quirk is the need to set the page selection bits in the control register to select page 1 addresses. Instead of duplicating the 8255 code, provide an (*io) callback and use the 8255 module to support this subdevice. This also removes the need for the private data in this driver.
