etnaviv: sync uapi header

Graphics / Mesa 3D Graphics Library / libdrm - Philipp Zabel [pengutronix.de] - 12 April 2017 05:58 EDT

Import the etnaviv header changes from kernel commits 9ad59fea162c ("drm/etnaviv: submit support for in-fences") and 78ec187f64fa ("drm/etnaviv: submit support for out-fences") for fence fd support.

The drm_etnaviv_gem_submit structure was extended to include a flags field, new flags for in-fence and out-fence fds and an input/output fence fd field.

This is one-way backwards compatible because old userspace code passing a short structure not including the flags field to new kernels will cause the remaining fields to be zero-filled. New userspace code must make sure to only pass the short structure to old kernels, though.

Not generated using make headers_install, since the drm/etnaviv_drm.h uapi header is not installed yet by the kernel. Copied from the airlied/drm-next commit 78ec187f64fa.
