V4L/DVB (9462): Allow specifying clock per device
Optimizations galore: Blistering barnacles! The KNC1 and friends like 90 Mhz clock much better rather than running at a higher throttle, for almost similar hardware. he exact cause unknown, possibly due to a lower voltage applied for the demod power supply.
