Drop the names! They are filled in by the v4l2 core.

It's a good idea to have an earlier patch that just removes these names
from the existing formats.

Don't set the name! Again, it's filled in by v4l2-ctrls.c.

I am not keen on arrays like this. First of all they duplicate struct v4l2_ctrl_config.
And secondly, I prefer it if you just call the v4l2_ctrl_new_std* functions to create
new controls.
