Update the sub-device drivers having a devnode enabled so they properly
handle the new framesamples field of struct v4l2_mbus_framefmt.
These drivers don't support compressed (entropy encoded) formats so the
framesamples field is simply initialized to 0, altogether with the
reserved structure member.

There is a few other drivers that expose a devnode (mt9p031, mt9t001,
mt9v032), but they already implicitly initialize the new data structure
field to 0, so they don't need to be touched.

Hi,

In this version the whole reserved field in struct v4l2_mbus_framefmt 
is also cleared, rather than setting only framesamples to 0.  

The omap3isp driver changes have been only compile tested.

Thanks,
Sylwester
