phy: sun9i-usb: add USB dependency

The sun9i usb phy driver calls of_usb_get_phy_mode(), which is not
available if USB is disabled:

drivers/built-in.o: In function `sun9i_usb_phy_probe':
:(.text+0x7fb0): undefined reference to `of_usb_get_phy_mode'

This adds a dependency to avoid the randconfig build errors.
