Pushed to git master after r-b on IRC (#intel-gfx) a few days ago. Thanks.

> Fix eglCreateImage() from a packed dma_buf surface with a non-zero offset
> to pixels data. In particular, this fixes support for planar YUV surfaces
> when they are individually mapped on a per-plane basis, i.e. when the
> OES_EGL_image_external is not used and user application wants to use its
> own shader code for composition, or processing on individual plane (OCL).
>
> v2: fixed check for tile boundary.
