usb: s3c-otg: Rename s3c_udc_probe() function

The driver is actually for the Designware DWC2 controller.
This patch is the second and final to rename global symbol,
the s3c_udc_probe() function.

The rename is done automatically:
	$ sed -i "s/s3c_udc_probe/dwc2_udc_probe/g" \
		`git grep s3c_udc_probe | cut -d : -f 1`
