The following two patches add support for the latest
revision of Hauppauge 461e that has moved from m88ds3103b
demod to m88ds3103c demod. The demod driver was reverse
egineered from a windows driver.
The m88ds3013c demod has some clocking changes and simplified
configuration.

Hauppauge 416e products have moved to using the 3103C satellite
demod. This demod behaves mostly like a 3103b, but has
different initialization, clocking, and lock operations.
This Linux code was reverse egineered entirely
using a Windows reference driver.
