[GIT,PULL,FOR,v4.21] Convert last remaining g/s_crop/cropcap drivers

This pull request converts the last remaining drivers that use g/s_crop and
cropcap to g/s_selection.

The first two patches do some minor code cleanup.

The third patch adds a new video_device flag to indicate that the driver
inverts the normal usage of g/s_crop/cropcap. This applies to the old
Samsung drivers that predate the Selection API and that abused the existing
crop API.

The next three patches do some code cleanup and prepare drivers for the
removal of g/s_crop and ensure that cropcap only returns the pixelaspect.

The next three patches convert the remaining Samsung drivers and set the
QUIRK flag for all three.

The final two patches remove vidioc_g/s_crop and rename vidioc_cropcap
to vidioc_g_pixelaspect.

This pull request is identical to the original RFC patch series:

https://www.mail-archive.com/linux-media@vger.kernel.org/msg135494.html

I was waiting for Samsung to test these changes, and Sylwester just did that.
Thank you very much, Sylwester! It's really nice to have a single driver
API for cropping and composing instead of having to deal with two.

Regards,

	Hans
