staging: comedi: vmk80xx: cleanup digital input subdevice init

Browse source 
Change the type for the digital input 'di_chans' boardinfo to match
the comedi_subdevice type it is set to. For aesthetic reasons, rename
the variable also.

Remove the SDF_GROUND flag from s->subdev_flags. This flag only has
meaning for analog subdevices.

Add the missing s->range_table for the subdevice.

Rename the (*insn_read) and (*insn_bits) functions for the digital
input subdevice to make grepping easier.

For aesthetic reasons, add some whitespace to the subdevice init.
