PATCH 1/1 dvb: mt352 frontend driver update

Hi,

This patch updates the mt352 driver to make it work with the Pinnacle 300i card. Some values are calculated at runtime now instead of having hard-coded defaults because the defaults don't fit for the Pinnacle, and some more small tweaks + fixes.

This was also discussed + accepted on the dvb list, going to submit directly because the saa7134 driver update depends on this.

Gerd
