The mask_peripheral_interrupt is called when channel wants to mask the
interrupt. Move this to suspend as this masking affects other channels
as well. Not touching unmask here and unmask would still be done of

Additionally, do not just call legacy suspend for runtime_suspend,

This patch add DMA drivers for DMA controllers in Langwell chipset
of Intel(R) Moorestown platform and DMA controllers in Penwell of
Intel(R) Medfield platfromThis patch adds support for Moorestown DMAC1 and DMAC2 controllers.
It also add support for Medfiled GP DMA and DMAC1 controllers.
These controllers supports memory to peripheral and peripheral to
memory transfers. It support only single block transfers.This driver is based on Kernel DMA engine
Anyone who wishes to use this controller should use DMA engine APIsThis controller exposes DMA_SLAVE capabilities and notifies the client drivers
of DMA transaction completionConfig option required to be enabled CONFIG_INTEL_MID_DMAC=y
