media: iris: implement set properties to firmware during streamon

Browse source 
During the stream on operation, set some mandatory properties on the
firmware to start a session. Set all v4l2 properties, which are set by
the client, on to firmware, which is prepared with the dependency graph.

* QC08C:
* Compressed Macro-tile format for NV12.
* Contains 4 planes in the following order -
* (A) Y_Meta_Plane
* (B) Y_UBWC_Plane
* (C) UV_Meta_Plane
* (D) UV_UBWC_Plane
*
* Y_Meta_Plane consists of meta information to decode compressed
* tile data in Y_UBWC_Plane.
* Y_UBWC_Plane consists of Y data in compressed macro-tile format.
* UBWC decoder block will use the Y_Meta_Plane data together with
* Y_UBWC_Plane data to produce loss-less uncompressed 8 bit Y samples.
*
* UV_Meta_Plane consists of meta information to decode compressed
* tile data in UV_UBWC_Plane.
* UV_UBWC_Plane consists of UV data in compressed macro-tile format.
* UBWC decoder block will use UV_Meta_Plane data together with
* UV_UBWC_Plane data to produce loss-less uncompressed 8 bit 2x2
* subsampled color difference samples.
*
* Each tile in Y_UBWC_Plane/UV_UBWC_Plane is independently decodable
* and randomly accessible. There is no dependency between tiles.
