2020-12-30libcamera: bayer_format: Add support for mbus codesJacopo Mondi
The existing implementation of the BayerFormat class supports converting a V4L2PixelFormat to a BayerFormat and vice-versa. Expand the class by adding support for converting a media bus code to a BayerFormat instance, by providing a conversion table and a dedicated static methods. Do not provide support for converting a BayerFormat to a media bus code as there's no 1-to-1 mapping between the two.

2020-12-11ipa: raspberrypi: Move initial frame drop decision to AGC/AWBDavid Plowman
Previously the CamHelper was returning the number of frames to drop (on account of AGC/AWB converging). This wasn't really appropriate, it's better for the algorithms to do it as they know how many frames they might need. The CamHelper::HideFramesStartup method should now just be returning the number of frames to hide because they're bad/invalid in some way, not worrying about the AGC/AWB. For many sensors, the correct value for this is zero. But the ov5647 needs updating as it must return 2.
