[PATCH 06/15] V4L: Add camera image stabilization control

[Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx>]

The V4L2_CID_IMAGE_STABILIZATION control allows to control the camera's
image stabilization feature. It can be used to enable/disable image
stabilization. If the image stabilization technique selection control
is needed, a separate menu control should be added.
