usb: EHCI, OHCI: Add configuration for the SH USB controller

The SH EHCI/OHCI driver hardcoded the CPU type in {ehci,ohci}-hcd.c.
So if we will add the new CPU, we had to add to the hcd driver each time.
The patch adds the CONFIG_USB_{EHCI,OHCI}_SH configuration. So if we
want to use the SH EHCI/OHCI, we only enable the configuration.
