[PATCH 05/18] Initial commit to support NetUP Dual DVB-T/C CI RF card.

From: Igor M. Liplianin
Date: Sat Jan 01 2011 - 04:30:26 EST

The card based on cx23885 PCI-e brige. Altera FPGA for CI,
multistandard demods stv0367 from STM for QAM & OFDM, Xcieve xc5000 tuners
and additional cx25840 for second analog input.
