pipeline: rpi: vc4: Allocate more embedded data buffers
If the pipeline runs out of embedded data buffers, then it will pass the frame to the IPA without the metadata. The IPA then has to use the delayed controls as inputs to the algorithms. This can cause problems with the subsequent algorithms if the sensor did not action the controls, especially with the autofocus as that doesn't have controls which can be passed in lieu of the metadata. Reduce the likelihood of this by increasing the number of embedded data buffers, as they are small so a generous number can be allocated.
