[GIT PULL FOR v3.18] cx23885: convert to the latest frameworks, including vb2

[Hans Verkuil <hverkuil@xs4all.nl>]

Hi Mauro,

This pull request converts the cx23885 driver to the latest V4L2 core
frameworks, removing about 1000 lines in the process.

It now passes the v4l2-compliance tests and, frankly, feels much more
robust.

I have tested this with my HVR-1800 board with video (compressed and
uncompressed), vbi, dvb and alsa, including several duration stress tests.

As usual, the vb2 conversion is a beast of a patch. But the vb2 conversion
affected video, vbi, dvb and alsa, so it's all over the place. And it is
all or nothing. See the commit log of that patch for some more information.

It also changed the risc code to simplify the code and to get rid of all
the timeouts that were copied-and-pasted from cx88. If anyone knows of a
reason for these timeouts, please let me know. I have tried to separate the
risc code changes from the vb2 changes, but that was impossible to get to
work with vb1.

I dropped the vb2 fix I included in my earlier pull request since that fix
will appear in v3.17 (i.e. before this driver is upstreamed) anyway.

Regards,

	Hans
