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).

the configuration operation in `data[2]` is not supported. Deal with

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.
