media: exynos4-is: Use v4l2_async_notifier_add_fwnode_remote_subdev

Browse source

The use of v4l2_async_notifier_add_subdev will be discouraged.
Drivers are instead encouraged to use a helper such as
v4l2_async_notifier_add_fwnode_remote_subdev.

This fixes a misuse of the API, as v4l2_async_notifier_add_subdev
should get a kmalloc'ed struct v4l2_async_subdev,
removing some boilerplate code while at it.

Use the appropriate helper v4l2_async_notifier_add_fwnode_remote_subdev,
which handles the needed setup, instead of open-coding it.
