Reading register values is slow

Description

It is so slow, I have to cache them in order to show them in the property view [1]. This could be a problem if changing register values affects other registers.

Yes, there is some problem remaining from the first revision of UFO camera requiring quite strange procedure with repetitions to read/write the registers. I can't really fix it in software.

OK. There is some speed degradation due to the hardware problems. However, the performance of register access will be always quite slow. There is quite many registers, non-DMA communication is pretty slow and there is communication with CMOSIS on top of it. I don't see how we can fix it.

For UI, we may just provide an "Update" button.
