V4L/DVB: cx2341x: Remove temporal filter control restriction

Browse Source 
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.

temporal filter is that it works well with full resolution
capturing, but not when the capture window is scaled (the
filter introduces a ghosting effect). So if the capture
window is scaled, then force the filter to 0.
For full resolution the filter really improves the video

suboptimal. */
