usb: renesas_usbhs: Remove dummy runtime PM callbacks

Browse Source 
Platform drivers don't need dummy runtime PM callbacks that just return
success in order to have runtime PM happening. This has changed since
following commits:

commit 05aa55dddb ("PM / Runtime: Lenient generic runtime pm callbacks")
commit 543f2503a9 ("PM / platform_bus: Allow runtime PM by default")
commit 8b313a38ec ("PM / Platform: Use generic runtime PM callbacks directly")
