usb: gadget: renesas_usbhs: bugfix: don't modify platform data

Browse Source 
renesas_usbhs has default callback functions and settings.
And it tried overwrite to platform private data
if platform doesn't have them.
So, if renesas_usbhs was compiled as module,
it will be hung-up on 2nd insmod.
This patch fixup it.
Special thanks to Bastian
