usb: core: Add PM runtime calls to usb_hcd_platform_shutdown
If ohci-platform is runtime suspended, we can currently get an "imprecise external abort" on reboot with ohci-platform loaded when PM runtime is implemented for the SoC. Let's fix this by adding PM runtime support to usb_hcd_platform_shutdown.
