powerpc/85xx: Fix warning for USB device-fixup

Fix USB device-fixup warning "node not found". This was occuring
because of static nature of start_offset variable

Static start_offset was storing offset of last node modified, and
was becoming issue if node fixup is carried multiple times,
resulting in "node not found" warning
