When performing a Comedi read instruction or setting up an asynchronous
command on the AI subdevice, clear any stale data on the A/D registers
by waiting for the Status register's BUSY bit to clear (if set) and then
if the FINISH or ERR bit is set, reading the A/D Data register twice to
clear the stale data.

The number of output clocks are configurable in the hardware.
Currently the driver registers the maximum number of outputs.
Fix the same by registering only the outputs that are there.
