dmaengine: at_xdmac: do not enable all cyclic channels

[ Upstream commit f8435befd81dd85b7b610598551fadf675849bc1 ]

Do not global enable all the cyclic channels in at_xdmac_resume(). Instead
save the global status in at_xdmac_suspend() and re-enable the cyclic
channel only if it was active before suspend.
