[PATCH] v4l: cx88 driver update 

This is a major update of the cx88 driver.  Main new feature is support
for the MPEG PCI function of the cx2388x chips.  The changes in detail:

  * A bunch of code restructions, to allow multiple modules (one per PCI
    function) work on top of the core module.
  * Add a new module with common code for the mpeg PCI function.
  * Add a new module to support mpeg encoder cards (connexant
    "blackbird" reference design).  That one is not much tested yet and
    may have bugs.  They can be easily workarounded by not loading the
    module through, it isn't needed to capture uncompressed video.
  * Add a new module to support DVB cards.  That one is better tested
    than the blackbird one, but it needs additional cutting-edge stuff
    from the dvb project, thats why it is disabled in Kconfig for now.
  * Several cleanups along the way: use kthread, use msleep(), drop some
    2.4.x compatibility code, move insmod options to 2.6 style, ...
  * adapt code to the video-buf changes.
  * suspend fixes.
  * as usual some new tv cards.
