ipa: rpi: vc4: data: Update tuning files for HDR
All the Raspberry Pi official camera tuning files are updated for HDR. As stated previously, there is no mechanism in the hardware for combining images so all this does is enable multi-channel AGC to produce short and long exposure frames. It will be up to the application to deal with them. The changes are identical in every tuning file. 1. The existing AGC tuning is duplicated twice so that we have 3 AGC channels. 2. The first is left alone (the default AGC channel), the second is tweaked to under-expose significantly (ev -3) and the final one is tweaked to over-exposure slightly (ev +0.5) 3. Control parameters are provided to the "rpi.hdr" algorithm to associate these AGC channels correctly with the HDR modes.
