This patch introduces the use of API function setup_timer
instead of driver specific function _init_timer as it is
the preferred and standard way to setup and set the timer.
To be compatible with the change, argument types of
referenced functions are changed. Also, definition of
function _init_timer is removed as it is no longer needed
after this change.
This is done using Coccinelle and semantic patch used for
this is as follows:

This driver module now only supports a single board type, so remove the
infrastructure for describing multiple board types. The comedi
"auto_attach" handler, `pci6208_auto_attach()` doesn't need to set the
comedi device's `board_name` or `board_ptr` members. The former is
automatically pointed to the comedi driver's `driver_name` by the core
comedi module, and the latter is not used anywhere else. The AO
subdevice's `n_chans` member can be set to 16 without looking it up in
the single element of `pci6208_boards[]`. There is no need to pass a
board index from the PCI device table to the "auto_attach" handler.

staging: comedi: adl_pci6208: combine PCI-6208 and PCI-6216 support
This module's PCI device table has separate PCI device IDs for PCI-6208
and PCI-6216, but in reality, both boards and their cPCI and PCIe
variants seem to have the same PCI device ID: 0x6208. The PCI subdevice
ID doesn't seem to help either.
It shouldn't do any harm to claim 16 AO channels for all devices
supported by this driver. The original PCI-6216 is just a PCI-6208 with
a daughter board providing the extra DACs. The data is clocked out to
the DACs serially with no acknowledgment. I assume this would still
happen when the DACs for the upper 8 channels are missing. Therefore,
change the driver to support a single board type with 16 AO channels,
and remove the suspicious PCI device ID for the PCI-6216.
Evidence about lack of a separate PCI device ID for PCI-6216 follows....

Kernel driver in use: adl_pci6208
Kernel modules: adl_pci6208
That system's "adl_pci6208" module only has the single PCI device ID for
the PCI-6208, but works for his PCIe-6216 except that it only supports 8
analog output channels instead of 16.
2. ADLINK's binary Linux module "pci6208.ko" (there is no separate
module for the PCI-6216) has a single alias:
alias: pci:v0000144Ad00006208sv*sd*bc*sc*i*
3. The MS Windows drivers include this set of hardware IDs for the
PCI-6208 series, with nothing more specific for the PCI-6216 (they are
all tied to the same name "ADLINK PCI-6208" and there is no mention of
PCI-6216):
staging: comedi: cb_pcimdas: add 8254 timer (pacer) support
The hardware has an 8254 timer/counter. Channe; 0 is available as a
generic counter/timer with the clock, gate, and output signals all
availabe on the main 37 pin connector. Channels 1 and 2 are used for
the pacer.
Add support for the 8254 timer.

staging: comedi: cb_pcimdas: tidy up cb_pcimdas_auto_attach()
For aesthetics, add some whitespace to the subdevice init.
Remove the unnecessary comments as well as the initialization of the
analog input subdevice 'len_chanlist'. That member is only used by
subdevices that support async commands.
For aesthetics, rename the analog input subdevice (*insn_read) function.

staging: comedi: cb_pcimdas: provide analog output range table
The analog output range is not programmable. The DAC ranges are
jumper-settable on the board. For aesthetics, provide a range table
for the user with all possible ranges.

staging: comedi: cb_pcimdas: support analog input programmable ranges
The hardware uses a switch on the board to select if the analog inputs
are bipolar or uinipolar. The gain is programmable to allow the following
input ranges:
Gain Bipolar Unipolar
0 +/-10V 0 to 10V
1 +/-5V 0 to 5V
2 +/-2.5V 0 to 2.5V
3 +/-1.25V 0 to 1.25V
Add the necessary code to the driver to allow the user to select the
desired range.

staging: comedi: cb_pcimdas: fix analog input channel configuration
The hardware uses a switch on the board to set the number of analog
input channels to either 16 single-ended or 8 differential channels.
Currently the switch setting is checked for every (*insn_read) operation
to validate the channel number.
Check the switch setting during the driver attach and initialize the
subdevice accordingly. This allows the core to handle the validation.

staging: comedi: ni_labpc_common: convert driver to use the comedi_8254 module
This driver uses an 8254 timer to generate the pacer clock used for analog
input data conversion. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.
The hardware actually has two 8254 devices. Timer B0 is the master for timed
conversions, timer B1 sets the scan pacing, and tmer A0 sets the conversion
pacing.
For the conversion, dev->pacer is used for the "B" timers and a new private
data member, dev->counter, is used for the "A" timers. All the divisor values
are stored in the dev->pacer.

staging: comedi: amplc_dio200_common: remove 'spinlock' from struct dio200_subdev_8254
Currently this driver uses a spinlock in the 8254 subdevice (*insn_read), (*insn_write),
and (*insn_config) functions. The comedi core checks if the subdevice is 'busy', in
parse_insn(), before any of the subdevice functions are attempted.
Remove the unnecessary spinlock.

The 'counter_number' in these functions is the comedi channel number from the
chanspec. The comedi core validates the chanspec before calling the driver
functions. Remove the unnecessary checks.
