[GIT PULL FOR v3.17] Add support for compound controls, use in solo/go7007

[Hans Verkuil <hverkuil@xs4all.nl>]

Hi Mauro,

This is the revised pull request for the compound control patch series that
you wanted. The only change made since the previous pull request is that the
max dimensions is reduced to 4.

The previous pull request is here:

https://patchwork.linuxtv.org/patch/24546/

I have added support for getting/setting multidimensional arrays to
v4l2-ctl here:

http://git.linuxtv.org/cgit.cgi/hverkuil/v4l-utils.git/log/?h=compound

I've also tested this with the solo and go7007 driver.

Regards,

	Hans
