V4L/DVB (12733): cx25821: some CodingStyle fixes

The original driver were generated with some dos editor, and used their
own coding style.

This patch does some automatic CodingStyle fixes, by running dos2unix
and Lindent tools.

More work still needs to be done for it to use upstream CodingStyle.
