gpio: 104-dio-48e: Implement and utilize register structures
Reduce magic numbers and improve code readability by implementing and
utilizing named register data structures. The 104-DIO-48E device
features an Intel 8255 compatible GPIO interface, so the i8255 GPIO
module is selected and utilized as well.
