Subject: [PATCH 1/2] usb: dwc3: exynos/omap: Change platform device IDs for
 no_op_xceive to AUTO

Multiple dwc3 probe calls try to allocate no_op_xceive platform
device. Having static IDs for these will throw sysfs error -EEXIST.
Changing these static platform device IDs to AUTO to enable
multiple dwc3 controller support on a SoC.
