powerpc/8xxx: Fix in USB device-tree fixup
Fix following issues in USB device-tree fixup: - returns when either dr_mode or phy_type not defined. This was terminating fix-up when only either property was defined in hwconfig string - updates dr_mode_type or dr_phy_type with junk value when their index is -1. Now these are updated only when their respective index is pointing to relevant types in modes[] and phys[] array - dr_mode_type and dr_phy_type were not NULL for each controller Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
