[meta-freescale] Nitrogen6x w/ OV5642

I'm on the Dylan branch and I've tried with both the default linux-boundary kernel as well as updating the .bb to use the latest 1.1.1 branch from boundary.  Looks like I'll have to dig a little deeper to see what's causing mfw_v4lsrc to fail (mfw_v4lsink works fine with a videotestsrc).
