Now that the PCI bus walking has been removed from the addi-data
drivers, the only differenced between addi_amcc_s9533.h and the
standard comedi amcc_s5933.h is the additional defines for the
apci3120 "ADDON RELATED ADDITIONS". Move those defines to
hwdrv_apci3120.c.
Modify all the addi-data drivers to then include the standard
comedi amcc_s5933.h header and delete the duplicate in addi-data.

This variable is only used in the detach of the addi-data boards to
indicate that the attach of the board was successful and that the reset
function can be called. We can use the dev->iobase variable to indicate
this instead. Once this variable is set the attach always completes.

This variable is only used as a flag to indicate that the pci device
has been enabled. Use the comedi_device 'iobase' variable to indicate
this instead. This is how it's normally handled in the comedi pci
drivers.
Make the call to comedi_pci_disabled() in i_ADDI_Detach() common
and move it to the end of the function. Both the if and else case
require it.

Use the comedi pci auto config mechanism to attach the addi-data
drivers. This allows removing all the PCI bus walking code.
Add a function, addi_find_boardinfo(), to find the driver specific
boardinfo. Since this function is currently in the common code we
have to use the pointer to the boardinfo that is stored in the
comedi_driver pointer.

This pci driver currently uses the comedi legacy attach mechanism
which allows the user to pass configuration options to the driver
when it is attached to the comedi subsystem. The use of these
configuration options is preventing the conversion of the addi-data
drivers to the comedi auto attach mechanism.
For the addi-data drivers, option[2] is used to enable/disable dma.
The default (0) action is to enable dma is the driver supports it.
Remove this configuration option and just enable dma if it is
supported.

The function pci_card_alloc() enables the pci device by calling
comedi_pci_enable() and then optionally calls pci_set_master() to
enable bus mastering for DMA.
Absorb this code directly into i_ADDI_Attach() as is more typical
for comedi PCI drivers. Also, remove the now unused i_Master
parameter from ptr_select_and_alloc_pci_card().

The io_addr array in the card data holds the PCI bar base addresses
returned by pci_resource_start(). Remove this array and just use
pci_resource_start() where needed in i_ADDI_Attach().
This also allows getting rid of i_pci_card_data() since it now
does nothing.

Some driver uses tasklet_disable in device remove/release process,
tasklet_disable will inc tasklet->count and return. If the tasklet
is not handled yet under some softirq pressure, the tasklet will be
placed on the tasklet_vec, never have a chance to be excuted. This might
lead to a heavy loaded ksoftirqd, wakeup with pending_softirq, but
tasklet is disabled. tasklet_kill should be used in this case.

Change the rtd520 driver to use the new `auto_attach()` method in
`struct comedi_driver` instead of the `attach_pci()` method. I plan to
remove the `attach_pci()` and `attach_usb()` methods once nothing is
using them.
Tag the new `rtd520_auto_attach()` function definition with `__devinit`
as it is only called during PCI probe.
