V4L/DVB (12923): SAA7164: Add support for the NXP SAA7164 silicon

This patch adds support for all of the known shipping Hauppauge HVR-2200
and HVR-2250 boards. Digital TV ATSC/QAM and DVB-T is enabled at this
time. Both tuners are supported.

Volatiles and typedefs need rework, the rest is coding style compliant.
