USB: OHCI: ohci-s3c2410: remove useless functions

The ohci_hcd_s3c2410_drv_probe and ohci_hcd_s3c2410_drv_remove
functions are removed as these are useless functions except calling
usb_hcd_s3c2410_probe and usb_hcd_s3c2410_remove functions.

The usb_hcd_s3c2410_probe function renamed to ohci_hcd_s3c2410_drv_probe
and usb_hcd_s3c2410_remove function renamed to ohci_hcd_s3c2410_drv_remove
for proper naming.
