Srinivas Kandagatla 0775bc462a slimbus: ngd: reset dma setup during runtime pm
[ Upstream commit d77772538f ]

During suspend/resume NGD remote instance is power cycled along
with remotely controlled bam dma engine.
So Reset the dma configuration during this suspend resume path
so that we are not dealing with any stale dma setup.

Without this transactions timeout after first suspend resume path.
