Kirk Lapray 04a45929e7 [PATCH] dvb: add nxt200x frontend module 
* nxt200x.c, nxt200x.h
- New frontend module that supports both NXT2002 and NXT2004.
  So far, only tested on NXT2004.  After testing on NXT2002, we should
  deprecate the nxt2002 module, and implement this one instead on the
  applicable cards.

* get_dvb_firmware:
- Added support for the NXT2004 firmware. This firmware works with both
  the ATI HDTV Wonder and the AVerTVHD MCE a180.
  This was originally written by Jean-Francois Thibert

* dvb-pll.c
- Fixed minimum frequency for tuv1236d. It seems that the data sheets
  are wrong.
