media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connection

Browse Source 
Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.

This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore

Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().

Before registering the notifier, bridge drivers must do two things: first, the
notifier must be initialized using the :c:func:`v4l2_async_nf_init`. Second,

bridge device needs for its operation. :c:func:`v4l2_async_nf_add_fwnode`,

:c:func:`v4l2_async_nf_add_fwnode_remote` and :c:func:`v4l2_async_nf_add_i2c`
are available for that purpose.
Async connection descriptors describe connections to external sub-devices the
drivers for which are not yet probed. Based on an async connection, a media data
or ancillary link may be created when the related sub-device becomes
available. There may be one or more async connections to a given sub-device but
this is not known at the time of adding the connections to the notifier. Async
connections are bound as matching async sub-devices are found, one by one.
Asynchronous sub-device registration helper for camera sensor drivers
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:c:func:`v4l2_async_register_subdev_sensor` is a helper function for sensor
drivers registering their own async sub-device, but it also registers a notifier
and further registers async sub-devices for lens and flash devices found in
drivers registering their own async connection, but it also registers a notifier
and further registers async connections for lens and flash devices found in
firmware. The notifier for the sub-device is unregistered and cleaned up with
the async sub-device, using :c:func:`v4l2_async_unregister_subdev`.
Asynchronous sub-device notifier example
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These functions allocate an async sub-device descriptor which is of type struct
:c:type:`v4l2_async_subdev` embedded in a driver-specific struct. The &struct
:c:type:`v4l2_async_subdev` shall be the first member of this struct:

Asynchronous sub-device notifier callbacks
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The V4L2 core will then use these descriptors to match asynchronously
registered subdevices to them. If a match is detected the ``.bound()``
notifier callback is called. After all subdevices have been located the
.complete() callback is called. When a subdevice is removed from the
system the .unbind() method is called. All three callbacks are optional.

Drivers can store any type of custom data in their driver-specific
:c:type:`v4l2_async_subdev` wrapper. If any of that data requires special
:c:type:`v4l2_async_connection` wrapper. If any of that data requires special
handling when the structure is freed, drivers must implement the ``.destroy()``
notifier callback. The framework will call it right before freeing the
