staging: comedi: aio_aio12_8: refactor boardininfo
This driver supports three board types with these differences:
104-AIO12-8 - eight 12-bit analog in, four 12-bit analog out
104-AI12-8 - eight 12-bit analog in
104-AO12-4 - four 12-bit analog out
Convert the boardinfo 'ai_nchan' and 'ao_nchan' into bit-field
flags 'has_ai' and 'has_ao' so save a bit of space.
