devm_input_allocate_device already sets the parent device to be that
passed to it, we also set this manually in arizona_extcon_probe. This
patch removes the redundant set from arizona_extcon_probe.

This patch add APIs to control the extcon device on extcon provider driver.
The extcon_dev_allocate() allocates the memory of extcon device and initializes
supported cables. And then extcon_dev_free() decrement the reference of the
device of extcon device and free the memory of the extcon device. This APIs
must need to implement devm_extcon_dev_allocate()/free() APIs.

Use the resource-managed extcon device register function (i.e.
devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device
is attached with this function, that extcon device is automatically unregistered
on driver detach. That reduces tiresome managing code.

In probe the driver queued delayed work for cable detection and
returned the result of queue_delayed_work() call. However the return
value of queue_delayed_work() does not indicate an error and in normal
condition it returns true which means successful work queue.
This effectively resulted in probe failure:
[ 2.088204] max14577-muic: probe of max77836-muic failed with error 1

Schedule delayed cable detection work on power efficient workqueue
so the scheduler won't wake up idle core for that work.
This extends the idle time for CPU cores and conserves power.
