ENGR00126343 v4l2 output: jitters come out when show frame too quick
It's easy to reproduce by run below cmd:
./mxc_v4l2_output.out -iw 320 -ih 240 -ow 1024 -oh 768 -fr 80 -d 3
qvga.yuv
For performance, we did not check display in IC interrupt handle before.
Output must sync to display.
In this patch:
1. make stream begin with one buffer.
2. change timer_work name to icbypass_work.
3. add display sync to timer interrupt handler.
