This driver still uses some of old broken code in hwdrv_apci1564.c
for the timer and counter subdevices. This code does not follow the
comedi API and does not work without additional patches to the core.
Tidy up the change-of-state support so that the dev->read_subdev
can be used to handle the interrupt events from the timer and counter
subdevices.
Rewrite the timer and counter subdevice support so that it follows
the comedi API.
NOTE: The datasheet I have from ADDI-DATA just describes the registers.
It does not have any functional information on the operation of the
timer or counter. The new code might not work _correctly_ but it at
least makes the subdevices work with the comedi API so that additional
testing can be done.
v2: mask the change-of-state input status in patch 1/6 at the request
of Ian Abbott
