Subject: [PATCH] dma: dw: Add suspend and resume handling for PCI mode
 DW_DMAC.

This is to disable/enable DW_DMAC hw during late suspend/early resume.
Since DMA is providing service to other clients (eg: SPI, HSUART),
we need to ensure DMA suspends after the clients and resume
before the clients are active.
