staging: comedi: addi_apci_3501: separate from addi_common.c
This driver is for a simple analog output board with 4 or 8, 14-bit outputs. The board also has 4 digital i/o channels (2 out/2 in) as well as a watchdog or timer. Using the addi-data "common" code in this driver introduces a lot of bloat. Copy the code in addi_common.c to this driver and remove the #include that caused it to be compiled with the driver. This will allow removing the bloat. Rename the auto_attach and detach functions so they have namespace associated with this driver.
