[yocto] [meta-raspberrypi] Using the camera

[Alexandru Vaduva]

It`s really hard to just offer impressions or suggestion.
Also I agree with the fact that the camera is ok cause I also tested it
with raspbian. No problems there.
But never the less I hope to keep me posted on any progress and
observations.
When I will have the time I will try some things of my own.
