V4L/DVB (6715): ivtv: Remove unnecessary register update
To reduce the number of display register accesses, the yuv code keeps track
of
the current video settings. Should there be a change in any single
parameter,
it will update the associated display registers to ensure everything is
displayed correctly.
The existing check also looks at the field order for the video. This is not
required, since field reversal does not require any display register
changes.
This patch removes the field order from the check.
