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
