Subject: [PATCH 5/7] dmaengine: ste_dma40: don't check for pm_runtime_suspended()

From: Narayanan G <narayanan.gopalakrishnan@...ricsson.com>

The check for runtime suspend is not needed during a regular suspend, as
the framework takes care of this.  This fixes the issue of DMA driver
not letting the system to go to deepsleep in the first attempt.
