MLK-13712 dmaengine: fsl-edma: restore edma registers for i.MX7ULP VLLS mode

EDMA controller will loss power on i.MX7ULP VLLS mode, then registers
are set to HW reset default value that cause EDMA cannot work after
system wake up. So the patch is to restore eDMA registers status after
system exit from VLLS mode.
