This driver only a cmd->start_src of TRIG_NOW or TRIG_INT. The cmd->start_arg
is trivially validated for both sources to be 0. For a TRIG_INT source, the
cmd->start_arg is actually the valid trig_num that is passed to the async
(*inttrig) callback.
Refactor the (*inttrig) function so that the cmd->start_arg is used to check
the trig_num instead of the open coded value.

This driver supports three cmd->start_src values, TRIG_NOW, TRIG_EXT, and
TRIG_INT. TRIG_NOW sources should always have an arg of 0 and arg for TRIG_EXT
sources is driver specific. This driver does not use the cmd->start_arg with
the TRIG_EXT source so a trivial value of 0 is good.
When the cmd->start_src is TRIG_INT the cmd->start_arg is actually the valid
trig_num that is passed to the async (*inttrig) callback. This driver allows
any value to be used and currently carries that value in the private data.
Refactor the (*do_cmdtest) so that the trivial validation of the cmd->start_arg
is clear.
Refactor the (*inttrig) so that the cmd->start_arg is used directly to check
the trig_num and remove the then unused 'ai_inttrig_start' member from the

The comedi_subdevices array is kzalloc()'d so the async command callbacks do
not need to be set to NULL when the analog output subdevice is initialized.
Also, remove the initialzation of the subdevice 'len_chanlist' since this

Due to a driver limitation, the (*do_cmdtest) for the analog input subdevice
overrides the cmd->chanlist_len to force single channel chanlists. But, the
cmd->scan_end_arg was already validated before this happens. Instead of
fixing the (*do_cmdtest) just set the subdevice len_chanlist to 1 to limit
the chanlist size. Move the comment also.

devpriv->iobase is currently being used to hold the iobase address used to
read/write the board's registers. The same address is stored in the
comedi_device dev->iobase. We use that instead. The eventual goal is to
decrease the driver's use of the struct addi_private, so that it may
eventually use a much slimmer specialized private struct instead, as the
other addi_apci_* drivers do.

The AS3722_GPIO_INV bit will always be blindly overwritten by
as3722_pinctrl_gpio_set_direction() and will be ignored when
setting the value of the GPIO in as3722_gpio_set() since the
enable_gpio_invert flag is never set. This will cause an
initially inverted GPIO to toggle when requested as an output,
which could be problematic if, for example, the GPIO controls
a critical regulator.
Instead of setting up the enable_gpio_invert flag, just leave
the invert bit alone and check it before setting the GPIO value.
