V4L/DVB: cx2341x: Remove temporal filter control restriction 

Since the change that stops the CX23415/6 firmware-intiiated secondary stream
appears to fix the temporal filter, it's now fully re-enabled for all capture
resolutions.

filter introduces a ghosting effect). So if the capture

For full resolution the filter really improves the video
