drm/omap: Add support for render nodes
Add support for render nodes in omap driver and allow required ioctls to be accessible via render nodes. This enables unprivileged clients to allocate resources like GEM buffers for rendering their content into. Mode setting (KMS ioctls) is not allowed using render nodes. These buffers are then shared with a previleged process (e.g compositor) that has mode setting access. An example of this use case is Android where the hardware composer is the only master and has mode setting access. Every other client then uses render node(e.g /dev/dri/renderD128 to allocate and use its buffers.
