phy: rockchip: fix Kconfig dependency more

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.
