During v4l2 output playback, there is performance issue after below
commit:
UBUNTU: SAUCE: (upstream) netdev/fec: fix performance impact from
mdio poll operation
Use common workqueue cause this issue, so create an own workqueue for
v4l2 output.

As CSI->MEM channel keeps on writing the buffer which is set to
ready latestly and raising up end of frame interrupts, the current
v4l2 capture realization mechanism is not appropriate for this channel.
This patch will update the idmac buffer to a dummy buffer whenever
there is no buffers queued by the user.

To preview with V4L2 overlay and capture at the same time may fail.
This patch implements workaround for this issue by enabling CSI after

This change makes us get rid of DIx_SYNC_DISP_ERR. The error sometimes
causes the backgound framebuffer reinitialized automatically, even if
we preview captured video on overlay framebuffer.

1. Blank BG during video play on FG:
./mxc_v4l2_output.out -iw 320 -ih 240 -ow 1024 -oh 768 -d 3 qvga.yuv
echo 1 > /sys/class/graphics/fb0/blank
echo 0 > /sys/class/graphics/fb0/blank
2. The same input and output (ic_bypass):
./mxc_v4l2_output.out -iw 320 -ih 240 -ow 320 -oh 240 -d 3 qvga.yuv
echo 1 > /sys/class/graphics/fb0/blank

Use DP to do CSC for preview on DPFG instead of using IC channel
so that we can get better performance. This change can make us
get rid of IC channel bandwidth limitation when using IC channel
to do upsizing from low resolution to high resolution and CSC.
This change doesn't touch V4L2 overlay for DPBG, because using DP
to do CSC will change the pixel format for DPBG(usually for GUI).
This change doesn't touch V4L2 capture, because users rarely do
upsizing with high multiple in this case.

There is one CSI crop improvement (engr117261) in v4l2 capture.
But the improvement is not suitable for tvin module since the
