6.13-stable review patch. If anyone has any objections, please let me know.

From: Arnd Bergmann arnd@arndb.de
[ Upstream commit fcf5d353b09b3fc212ab24b89ef23a7a8f7b308e ]
A previous patch ensured that USB Type C connector support is enabled, but it is still possible to build the phy driver without enabling CONFIG_USB (host support) or CONFIG_USB_GADGET (device support), and in that case the common helper functions are unavailable:
aarch64-linux-ld: drivers/phy/rockchip/phy-rockchip-usbdp.o: in function `rk_udphy_probe': phy-rockchip-usbdp.c:(.text+0xe74): undefined reference to `usb_get_maximum_speed'
Select CONFIG_USB_COMMON directly here, like we do in some other phy drivers, to make sure this is available even when actual USB support is disabled or in a loadable module that cannot be reached from a built-in phy driver.
