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 field.
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.

Changes since v4:
- in the try format functions use local copies of only width, height, code
rather that caching whole struct v4l2_mbus_framefmt
Changes since v3:
- use local copy of the format data structure to clear all structure
members which are unused by a driver, in way that it don't break
after new fields are added to struct v4l2_mbus_framefmt;
The omap3isp changes are only compile tested. Thus I'd like to ask someone
who has access to the hardware to test the patch and provide Ack or
Tested-by :)
Thanks,
Sylwester
