gpio: 104-dio-48e: Utilize the ISA bus driver
The ACCES 104-DIO-48E series communicates via the ISA bus. As such, it is more appropriate to use the ISA bus driver over the platform driver to control the ACCES 104-DIO-48E GPIO driver. This patch also adds support for multiple devices via the base and irq module array parameters. Each element of the base array corresponds to a discrete device; each element of the irq array corresponds to the respective device addressed in the respective base array element.
