The number of subdevices needed by a given board supported by this
driver can cary from 2 (for the apci3500) to a maximum of 5. Currently
this driver always allocates 7 subdevices and sets the subdevice type
to COMEDI_SUBD_UNUSED for the ones that are not needed.

Calculate the actual number of needed subdevices from the boardinfo
and only allocate and setup the ones that are used.

The analog input subdevice support functions in hwdrv_apci3xxx.c
do not follow the comedi API.

The (*insn_config) function overrides the INSN_CONFIG_DIO_INPUT
instruction as an internal APCI3XXX_CONFIGURATION instruction. The
APCI3XXX_CONFIGURATION instruction requires 4 data parameters but
the comedi core sanity checks the INSN_CONFIG_DIO_INPUT instruction
which only has 1 data parameter. Because of this the (*insn_config)
function can never be called.

The (*insn_read) function is supposed to do "one-shot" or "software-
triggered" reads and return the data. The function in hwdrv_apci3xxx.c
does do this but it also is used to optionally start a "hardware-
triggered" conversion. Hardware-triggered conversions should be done
with the comedi_async command functions.

Delete the hwrdv_apci3xxx.c file and fix the analog input subdevice
in the driver by:

1) add a new (*insn_read) function for "one-shot" reads
2) implement the (*do_cmdtest) and (*do_cmd) functions for
   "hardware-triggered" asyncronous reads
3) fix the interrupt handler to return the read data via the
   comedi_async buffer

The number of differential analog input channels is always half the
number of single-ended channels, 'ai_n_chan', or all the channels
if the board does not support single-ended channels. We can use the
'ai_subdev_flags' boardinfo to determine if the board does not support
single-ended channels.

To simplify the boardinfo, remove the 'i_NbrAiChannelDiff' and just
use 'ai_n_chan' to specify the number of channels.
