The ipack subsystem is cleaned up enough to now move out of the staging
tree, and into drivers/ipack.

 * Can be turned on/off at runtime
 * Provides full USB-level traffic
 * tcpdump and wireshark support for powerful analysis
 * No driver-specific code is required

Apart from the somewhat unnecessary `BUG_ON()` calls,
`comedi_pci_auto_config()` and `comedi_usb_auto_config()` are just
one-line wrappers around `comedi_auto_config()`, and
`comedi_pci_auto_unconfig()` and `comedi_usb_auto_unconfig()` are just
one-line wrappers around `comedi_auto_unconfig()`.  Convert them to
inline functions and remove the `BUG_ON()` calls.

No comedi drivers set the `attach_pci()` or `attach_usb()` handlers in
their `struct comedi_driver` any longer as they have all been replaced
with an `auto_attach()` handler.  Also, no code calls the `attach_pci()`
or `attach_usb()` handlers any longer.  Remove them from `struct
comedi_driver`.

`comedi_auto_config()` just calls internal function
`comedi_auto_config_helper()`, passing it a wrapper function
`comedi_auto_config_wrapper()` to handle the specifics of checking and
calling the low-level comedi driver's `auto_attach()` handler.

Since there are no other callers of `comedi_auto_config_helper()` or
`comedi_auto_config_wrapper()`, combine everything into the single
exported function `comedi_auto_config()`.

Change the ordering of the check for existence of the low-level comedi
driver's `auto_attach()` handler and the allocation of the comedi minor
device number.  This means the log message warning of the absence of the
handler now has to be refer to the hardware device instead of the
not-yet-allocated comedi device.

There is no need for `comedi_pci_auto_config()` and
`comedi_usb_auto_config()` to check that `driver->auto_attach` is
non-null before calling `comedi_auto_attach()` as this check is done by

`comedi_auto_config_wrapper()`).  Remove the unnecessary checks.
