[yocto] [meta-raspberrypi][PATCH 5/8] Support for vc4 graphics driver: upgrade 4.4 kernel to 4.4.10

[Herve Jourdain]

Hi Andrei,

I have a v3 cooking, I will release it shortly after I have a good solution
for the management of the dtbo - I guess I've just managed to get something
working, but I need a few more tests.
I'll try to take all your remarks into account, as well as those by Andreas
and Khem.

Herve
