Remove processMrw.pl's PAU rebsae workaround
Remove processMrw.pl's PAU rebsae workaround

Older MRWs put PAU targets as children of IOHS, so a workaround was added
to processMrw.pl to rebase that target as a child of PAUC instead.  Now that
MRWs correctly model this relationship, this commit removes the workaround.
