enable standard v4l2 driver on freescale i.mx
Freescale has v4l2 driver support on IPU for i.mx, but it's not so standarlize. The blueprint is target to standarlize the v4l2 driver for i.mx and possible add support for dma-buf support on v4l2 driver.
Headline: Standarlize and implement v4l2 driver for i.mx and add dma-buf support.
Got kenrel source for i.mx (both Freescale internal and linaro): DONE
Analysis ioctl interface need to be implement or standarlize: INPROGRESS
Fix v4l2 driver for v4l2: TODO
Add dma-buf support: TODO
