media: m88ds3103: Implement 3103c chip support

Browse Source 
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.
