[PATCH] USB: ohci, move ppc asic tweaks nearer pci
This should fix a suspend/resume issues that appear with OHCI on some
PPC hardware. The PCI layer should doesn't have the hooks needed for
such ASIC-specific hooks (in this case, software clock gating), so
this moves the code to do that into hcd-pci.c ... where it can be
done after the relevant PCI PM state transition (to/from D3).
