The (*insn_read) and (*insn_write) functions for all the subdevices
in this driver are the same except for the 'offset' that is added
to the iobase and channel to read/write a register on the board.

Pass the 'offset' in s->private so we can use the same (*insn_read)
and (*insn->write) functions for all the subdevices.

Also, fix the (*insn_read) and (*insn_write) functions so they work
correctly. The comedi core expects them to read/write insn->n data
values and then return the number of values used.

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

Remove the dev_info() noise at the end of the attach.

The low-level i/o functions in this driver simply read/write a
register based on the channel in insn->chanspec and an offset.

Create a macro, PCI8164_AXIS(), that takes the channel number as
a parameter and returns the register value.

Remove the switch() statements used to figure out the 'axis_reg'
and use the new macro instead.

The dev_dbg() messages in the adl_pci8164_insn_{read,out} functions
output the 'data' that was read/write to the device. Two 'data' values
are always printed, data[0] and data[1].

The 'data' pointer points to an array of unsigned int values. The number
of values in the array is indicated by insn->n. The number of data
elements is never checked so the dev_dbg() could be trying to access
a 'data' element that is invalid.

Instead of fixing the dev_dbg() just remove them. They are really just
added noise.
