staging: comedi: me4000: remove struct me4000_ai_info
authorH Hartley Sweeten <hartleys@visionengravers.com>

The me4000_aio_info in the boardinfo struct is used to indicate
the number of analog input channels and a couple other details
about them. Remove the extra struct and absorb the data into the
boardinfo struct.
