The IIO core handles a trigger ops with all NULL callbacks the
same as if the trigger ops itself was NULL.
Remove the empty trigger ops from the interrupt trigger driver to slightly
reduce the boilerplate code. Object size of the driver module is also
slightly reduced.

When allocated with [devm_]iio_trigger_alloc(), set trig device parent to
the device the trigger is allocated for by default.
It can always be reassigned in the probe routine.
Change iio_trigger_alloc() API to add the device pointer to be coherent
with devm_iio_trigger_alloc, using similar interface to
iio_device_alloc().

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.
Note that stm32-timer-trigger has expanded rather beyond triggers
(to include encoder input counting for example) and hence has an
iio_info structure.

These stand-alone trigger drivers were using iio_trigger_put()
where they should have been using iio_trigger_free(). The
iio_trigger_put() adds a module_put which is bad since they
never did a module_get.
In the sysfs driver, module_get/put's are used as triggers are
added & removed. This extra module_put() occurs on an error path
in the probe routine (probably rare).
In the bfin-timer & interrupt trigger drivers, the module resources
are not explicitly managed, so it's doing a put on something that
was never get'd. It occurs on the probe error path and on the
remove path (not so rare).
Tested with the sysfs trigger driver.
The bfin & interrupt drivers were build tested & inspected only.

This patch removes the .owner field for drivers which use the
platform_driver_register api because this is overriden in
_platform_driver_register.

The name includes irq_res->start which of type resource_size_t not integer.
We could in theory use %pa for this but then it would be in hex and also
that causes a warning about incorrect types anyway. Hence just
use the irq local variable we assigned the line above.

This is now a very simple trigger indeed but useful in many common cases.
