media: v4l: async: Rename async nf functions, clean up long lines 

Rename V4L2 async notifier functions, replacing "notifier" with "nf" and
removing "_subdev" at the end of the function names adding subdevs as you
can only add subdevs to a notifier. Also wrap and otherwise clean up long
lines.

picked up by bridge drivers.
Bridge drivers in turn have to register a notifier object. This is
performed using the :c:func:`v4l2_async_notifier_register` call. To
performed using the :c:func:`v4l2_async_nf_register` call. To
unregister the notifier the driver has to call
:c:func:`v4l2_async_notifier_unregister`. The former of the two functions
:c:func:`v4l2_async_nf_unregister`. The former of the two functions
takes two arguments: a pointer to struct :c:type:`v4l2_device` and a
pointer to struct :c:type:`v4l2_async_notifier`.
Before registering the notifier, bridge drivers must do two things: first, the
notifier must be initialized using the :c:func:`v4l2_async_notifier_init`.
notifier must be initialized using the :c:func:`v4l2_async_nf_init`.
Second, bridge drivers can then begin to form a list of subdevice descriptors
that the bridge device needs for its operation. Several functions are available
to add subdevice descriptors to a notifier, depending on the type of device and
the needs of the driver.
:c:func:`v4l2_async_notifier_add_fwnode_remote_subdev` and
:c:func:`v4l2_async_notifier_add_i2c_subdev` are for bridge and ISP drivers for
:c:func:`v4l2_async_nf_add_fwnode_remote` and
