[imx219] Support 2x2 binning

[cristiklein]

This patch adds a new mode to the IMX219 sensor. The sensor returns a 1640x1232 image by returning the average over 4 pixels, 2 horizontally and 2 vertically.

Dear, cristiklein
Thanks for your commits. May I know which image version of Tinker-OS do you test with this commit ?

[cristiklein]

Dear Huang, I tested it on top of the latest TinkerOS 2.0.8.

Dear, cristiklein
Thanks for your quickly reply. But we can not use gstreamer to enable the 2x2 binning mode. Can you share your gstreamer command to us ?

Hi, I set the sensor mode using media-ctl. Gstreamer got a regular 1640x1232 video stream. I used no ISP 3A, since that requires updating /etc/cam_iq/IMX219.xml, and I currently lack the knowledge to do that myself. I set gain an exposure using v4l2-ctl. I can come back later with the exact command.

Hi, Here are the commands I used for testing: ``` media-ctl --set-v4l2 '"imx219 2-0010":0[ fmt:SRGGB10_1X10/1640x1232]' gst-launch-1.0 rkcamsrc device=/dev/vide o1 ! video/x-raw,width=1640,height=1232,format=NV12,framerat e=15/1 ! queue name=to-jpegenc ! jpegenc ! multipartmux ! tc pserversink host=127.0.0.1 port=9999 ``` Let me know what other information I can provide you with.

Dear, cristiklein
Thanks for your commit. We will try to enable the 3A of this binning mode.

Thanks Huang!
