Previously, possible digital gains were just 1x, 2x and 4x. These
coarse gains were not sufficient in fine-tuning the image capture.
Now, digital gain range is [0, 16x] with each step 1/1024, default 1x.
This is achieved through OV13858 MWB R/G/B gain controls.

UVC defines a method of handling asynchronous controls, which sends a
USB packet over the interrupt pipe. This patch implements support for
such packets by sending a control event to the user. Since this can
involve USB traffic and, therefore, scheduling, this has to be done
in a work queue.

Hi Sakari,
Is the lens-focus phandle specific to voice-coil controllers? What about
motor-controlled focus systems? What when there are multiple motors? E.g.
one for the focus, one for the iris control (yes, we have that).
What if you have two sensors (stereoscopic) controlled by one motor?
