cx25821: convert to vb2

This pull request converts this driver to the vb2 framework.

I have tested video capture with my cx25821 board. Audio capture DMA works as well, but since my board doesn't have an audio line-in I couldn't test it with actual audio.

This patch series also removes the last case of btcx-risc abuse, so that module can now be merged again with bttv, which is where it belongs.

Regards,

Hans
