staging: comedi: addi_apci_3501: cleanup the digital input subdevice

The board supported by this driver has 2 digital input. Remove the
conditional and always init the subdevice.

Also, move the subdevice insn_bits function pointer as well as the
n_chan out of the boardinfo and use them to initialize the subdevice
directly.

Since devpriv->s_EeParameters.i_NbrDiChannel for the digital input
subdevice is no longer being used, remove initialization of it also.

Copy the apci3501_di_insn_bits() function from hwrdv_apci3501.c into
the main driver file.

Fix the subdev_flags for the subdevice. The only required flag is
SDF_READABLE. The SDF_GROUND and SDF_COMMON flags only have meaning
for analog subdevices.

Remove the len_chanlist initialization, it only has meaning for subdevices
that support commands.

Remove the io_bits initialization, it only has meaning for digital i/o
subdevices that have configurable outputs.
