Steven Toth c771261330 V4L/DVB (7006): cx23885: Track the board clock frequency and allow overrides 
The cx23885/6/8 all have different clock rates, this patch allows
the core to compensate, and developers to allow vendor specific
overrides. This patches will be used by future analog video
and encoder patches.
