[PATCH v5] modify videobuf2-dma-contig and update sta2x11_vip

[Federico Vaga]

We have some new ideas for this new complex architecture (sta2x11) that can 
fix our DMA problems without change the existent code. Obviously, ideas arrive 
when I already sent the patches. Anyway, consider this patch series as an RFC. 
They are not ready for the mainline. I take some time to investigate on the 
architecture side of the project to try to fix our problem.

Anyway, if you consider interesting configure the gfp flags for dma-contig, I 
can propose a v6 series which correct the alloc coherent line.

Sorry for the spam :(
