mpc8xxx: USB: Removed reenablement of its interface

To prepare for the 85xx USB support, which requires interface enablement
only once in (specified) order, no different than instructions for
enabling the interface under 83xx.  It is unknown why the original author
enabled the interface twice (checked for references in errata, etc).
