sunxi: usb: Remove sunxi_usbc_get_io_base function
This is the only function left in sunxi/usbc.c which is not phy related, so remove it. This is a preparation patch for turning the usbc.c code into a proper usb phy driver. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
