staging: comedi: addi-data: use attach_pci callback
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 function calls comedi_pci_disable() to disable the pci
device when detached. It's only called from i_ADDI_Detach().
Move the code there and delete the function.

staging: comedi: addi-data: remove attach option to disable dma
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.

staging: comedi: addi-data: absorb pci_card_alloc() into i_ADDI_Attach()
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().
