ENGR00161526 mxc v4l2 output: 720p ic bypass output may failed in block
Repeat play with below cmdline:
/unit_tests/mxc_v4l2_output.out -iw 1280 -ih 720 -ow 1280 -oh
720 -fr 10 -l 1 /unit_tests/720p.yuv
Found the ipu update offset function cause this issue, it can be
work-around by setting it only when value changed.
