USB: OHCI: ohci-omap: remove useless functions

The ohci_hcd_omap_drv_probe and ohci_hcd_omap_drv_remove
functions are removed as these are useless functions except calling
usb_hcd_omap_probe and usb_hcd_omap_remove functions.

The usb_hcd_omap_probe function renamed to ohci_hcd_omap_probe
and usb_hcd_omap_remove function renamed to ohci_hcd_omap_remove
for proper naming.
