dwc3 initiated xhci probe problem in arm64 4.4 kernel due to DMA setup

dwc3 is in dual-role, with "synopsys,dwc3" specified in DT. When xhci is probed, initiated from dwc3/host.c (not DT), we get : xhci-hcd: probe of xhci-hcd.7.auto failed with error -5 This -EIO error originated from inside dma_set_mask() down in include/asm-generic/dma-mapping-common.h If
