dwc3 linux usb3.0 driver架构
在dwc3_host_init函数的最后调用platform_device_add(xhci)添加platform device（xhci-hcd），用于匹配xHCI driver（xHCI driver platform_driver usb_xhci_driver = { .probe = xhci_plat_probe, .remove = xhci_plat_remove, .driver = { .name = "xhci-hcd usb_xhci_driver); } 1）在xhci_plat_init中调用platform_driver_register(&usb_xhci_driver)注册platform driver（"xhci-hcd "） 2）首先根据name="xhci-hcd"匹配到platform device后，执行xhci_plat_probe 3）在xhci_plat_probe中，进行xHCI的初始化，最后添加到usb

USB总线-Linux内核USB3.0控制器初始化代码分析（三）
xhci指向了usb作为主机模式时的数据结构，使用platform_device表示，主机模式的驱动是platform_driver，两个会通过设备名称xhci-hcd匹配，具体在分析主机驱动时说明。
