Tobias Jakobi 134a0fe984 drm/exynos: g2d: wait for engine to finish 
While the engine works on a runqueue node it does memory access to
the buffers associated with that node.
Make sure that the engine is idle when g2d_close() and/or
g2d_remove() are called, i.e. buffer associated with the process (for
g2d_close()), or all buffers (for g2d_remove()) can be safely be
unmapped.

We have to take into account that the engine might be in an undefined
state, i.e. it hangs and doesn't become idle. In this case, we issue
a hardware reset to return the hardware and the driver context into a
proper state.
