Update all call sites of generic_setup_phy() as well, all of which are USB host related, except for DM test which now behaves as a USB host test. Note that if the PHY driver does not implement the .set_mode callback, generic_phy_set_mode() call returns 0 and does not error out, so this should not break any existing systems.
