firesat: update isochronous interface, add CI support

I have finally managed to get the CI support for the card working. The
implementation is a bare minimum to get encrypted channels to work in
kaffeine. It works fine with my T/CI card. Now and then I get an AVC
timeout and have to retune a channel in order to get it to work. Once
the CAM seemed to hang so I needed to remove and insert it again. I.e.
there are a number of glitches.

The latest version contains the following changes:

  - Implemented the new hpsb iso interface so that data can be received
    from the card
  - Reduced some timers for demux setup which caused scanning to timeout
  - Added possibility to unload driver
  - Added support for getting C/N ratio
  - Added two debug parameters to the driver; ca_debug and
    avc_comm_debug.
  - Added CI support that works for me in kaffeine
  - Started working on CI MMI support. It now supports:
      o Enter menu
      o Receiving MMI objects
  - Added support for 64-bit platforms
  - Corrected DVB-C modulations problems
