The board supported by this driver always has a digital input subdevice.
Remove the boardinfo for it and just open-code the relevant data in the
subdevice init.
Remove the SDF_GROUND and SDF_COMMON from the subdevice 'subdev_flags'.
These flags only have meaning for analog input/output subdevices.
Remove the subdevice 'len_chanlist' initialization. This variable only
has meaning for subdevices that support asynchronous commands.
Remove the subdevice 'io_bits' initialization. Digital input subdevices
don't use this variable.
Remove the subdevice function pointers that evaluate to NULL based on the
boardinfo data.
Move the apci2200_di_insn_bits() function from the hwdrv_apci2200.c file
into the main driver file.
For aesthetic reasons, rename the #define used for the register used to
read the digital inputs.
