ARM: common: edma: add suspend resume hook
This patch makes the edma driver resume correctly after suspend. Tested on an AM33xx platform with cyclic audio streams and omap_hsmmc. All information can be reconstructed by already known runtime information. As we now use some functions that were previously only used from __init context, annotations had to be dropped.
