2010-05-24ENGR00120807 V4L2 capture:Change the mechanism for CSI->MEM captureLiu Ying
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.

2010-05-24ENGR00119034 V4L2 overlay:Use DP to do CSC for preview on DPFGLiu Ying
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.
