[PATCH v3 0/2] usb:dwc3: Enable USB DWC3 support for 64-bit system

When CONFIG_DMA_CMA is not set, the coherent mask is not set.
These patches enable the USB DWC3 driver to set the coherent mask
correctly by first set coherent DMA mask to 64-bit. If this
failed, attempt again with 32-bit.
In addition, pass the archdata to the xhci-hcd child so that
xhci-hcd can configure DMA operations correctly.
