USB: phy: am335x-control: fix device and of_node leaks
commit 015105b12183556771e111e93f5266851e7c5582 upstream. Make sure to drop the references taken by of_parse_phandle() and bus_find_device() before returning from am335x_get_phy_control(). Note that there is no guarantee that the devres-managed struct phy_control will be valid for the lifetime of the sibling phy device regardless of this change.
