staging: comedi: skel: do auto-attachment of PCI devices
This driver is an example of how to write a Comedi driver and includes
some code for handling PCI devices, but not very much. It calls
`comedi_pci_auto_config()` at PCI probe time. That normally expects to
call the comedi driver's `auto_attach()` hook (or the deprecated
`attach_pci()` hook), but will fall back to using the `attach()` hook
that should only be used for attaching devices "manually" via the
`COMEDI_DEVCONFIG` ioctl.
Add an `auto_attach()` hook (`skel_auto_attach()`) to handle
auto-attachment of supported PCI devices. Add comments to the
`attach()` hook (`skel_attach()`) to indicate that it shouldn't
generally allow PCI devices to be attached that way (and probably isn't
needed at all for PCI-only Comedi drivers). Add code to the `detach()`
hook (`skel_detach()`) to disable PCI devices enabled by the
`auto_attach()` hook.
`skel_auto_attach()` calls new function `skel_find_pci_board()` to find
a matching element in `skel_boards[]`. PCI device ID information has
been added to `skel_boards[]` to give the function something to look
for.
Remove the `pci_dev` member of `struct skel_private` as drivers now use
the `hw_dev` member of `struct comedi_device` to get at the PCI device.

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.
