staging: comedi: don't check driver->auto_attach

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()` itself (actually by
`comedi_auto_config_wrapper()`).  Remove the unnecessary checks.

staging: comedi: don't call attach_usb handler

All the Comedi drivers that call `comedi_usb_auto_config()` have

existence of the `attach_usb()` handler any more.  Remove this check and
the code that calls it.

staging: comedi: define operations for INSN_CONFIG_DIGITAL_TRIG

The 'addi_apci_1032' driver recently started supporting the
`INSN_CONFIG_DIGITAL_TRIG` configuration instruction, but as no other
drivers were using it before, there was no existing practice of how the
instruction should look.

Define the format to be something a bit more configurable.  In
particular, a subdevice might have more than one trigger requiring an ID
and/or `COMEDI_EV_...` flags to disambiguate them, a trigger might have
more than 32 inputs, and a trigger might need several
`INSN_CONFIG_DIGITAL_TRIG` configuration instructions to configure
completely (if there are more than 32 inputs or if it uses a combination
of edge-triggered and level-triggered inputs).

Conform to the new definition of the `INSN_CONFIG_DIGITAL_TRIG`
configuration instruction.

Return an error if the 'trigger number' in `data[1]` is non-zero or if
the configuration operation in `data[2]` is not supported.  Deal with
the 'left-shift' amount in `data[3]`.

The trigger's input channels can only be configured as a set of rising
and falling edges ('OR' mode) or as a set of high and low levels ('AND'
mode).  Preserve the old input channels to the right of the 'left-shift'
value except when switching modes.

(The 'left-shift' support is a bit of an overkill for this driver since
the trigger only has 16 input channels.)

staging: comedi: comedi_fc.h: introduce new helpers for do_cmdtest step 3

Step 3 of the do_cmdtest functions validates the arguments for the
command to be executed. Most of these are simple tests to see if the
argument "is" a value, a "min" value, or a "max" value. Each of these
tests then clamps the argument to the value if it fails the test.

Introduce three new helper functions in comedi_fc.h to handle these
tests and remove the boilerplate code from the drivers.

The new helper functions are:

cfc_check_trigger_arg_is()  - argument must be == the value
cfc_check_trigger_arg_min() - argument must be >= the value
cfc_check_trigger_arg_max() - argument must be <= the value

All of these helpers set the argument to the value and return -EINVAL
if the validation fails.
