This patch adds role switch support for R-Car SoCs into the USB 3.0 peripheral driver. Some R-Car SoCs (e.g. R-Car H3) have USB 3.0 dual-role device controller which has the USB 3.0 xHCI host and Renesas USB 3.0 peripheral. Unfortunately, the mode change register (DRD_CON) contains the USB 3.0 peripheral controller side only. So, this renesas_usb3 driver manages the DRD_CON now. However, in peripheral mode, the host should stop. Also the host hardware needs to reinitialize its own registers when the mode changes from peripheral to host mode. Otherwise, the host cannot work correctly (e.g. detect a device as high-speed). To achieve this reinitialization by a driver, this driver also registers a role switch driver to manage the DRD_CON and get a device pointer of usb 3.0 host from "companion" property of OF. Then, when the usb role is changed, renesas_usb3_role_switch_set() will attach/release the xhci-plat driver to reinitialize the host hardware.
