This commit adds DAM controller present on Actions S700, it differs from
S900 in terms of number of dma channels and requests.

Changes since v2:
	* added power-domain property as sps
          is enabled now and DMA needs it.
Changes since v1:
        * No Change.
Changes since RFC:
        * No Change.
