The PCB layout can effect the optimal IF.

This patch doesn't prevent customizing the IF. It will just avoid the need of setting the IF on both xc5000 and drx-k. Basically, (some) DRX-K based boards use different IF's depending on the bandwidth and delivery system type. Instead of adding a complex logic that would allow such kind of IF adjustments on both, drx-k will simply inquire the tuner about what IF is currently used. All that said, if somebody actually intends to hack on it, I can look up what the correct IF is for the 520e.
