ipa: rkisp1: Support raw capture in IPA operations
The RkISP1 can capture raw frames by bypassing the ISP. In that mode, the ISP will not produce statistics nor consume parameters. Most algorithms will thus be unable to run, with one exception: the AGC will still be able to configure the sensor exposure time and analog gain in manual mode. To prepare for this, add the ability to disable algorithms for the duration of the capture session based on the camera configuration. Individual algorithms report whether they support raw formats at construction time, and the IPA module disables algorithms in configure() based on the stream configurations. Disabled algorithms are skipped during the capture session in the processStatsBuffer() operation. As the ISP doesn't produce statistics, don't try to access the stats buffer. There is no need for similar logic in fillParamsBuffer() as that operation won't be called for raw capture. All algorithms report not supporting raw capture by default. Raw support in AGC will be added separately. The feature is implemented in the RkISP1 module without any support from libipa at this point to avoid designing a generic API based on a single user. This may be changed in the future.
