Subject: [PATCH] usb: udc: tegra: select USB_ROLE_SWITCH
Without this, this new driver fails to link:
drivers/usb/gadget/udc/tegra-xudc.o: In function `tegra_xudc_remove':
tegra-xudc.c:(.text+0x19d4): undefined reference to `usb_role_switch_unregister'
drivers/usb/gadget/udc/tegra-xudc.o: In function `tegra_xudc_probe':
tegra-xudc.c:(.text+0x2a34): undefined reference to `usb_role_switch_register'
drivers/usb/gadget/udc/tegra-xudc.o: In function `tegra_xudc_usb_role_sw_work':
tegra-xudc.c:(.text+0x4b64): undefined reference to `usb_role_switch_get_role'
