[PATCH v2 2/2] libcamera: libipa: camera_sensor: Add Sony IMX335 sensor properties

[Umang Jain]

From: Kieran Bingham <kieran.bingham at ideasonboard.com>

Provide the Sony IMX335 camera sensor properties and registration
with libipa for the gain code helpers.

The test patterns exposed by the IMX335 do not map well to the current
set of test pattern controls supplied by libcamera. These are left
inentionally unimplemented.
