[PATCH 1/2] usb: ohci-sa1111: remove machine_has_neponset()

The neponset is a daughter board for the Assabet platform, which has a SA chip on it. If we're initialising the SA OHCI, and we're part of a neponset, the host platform must be an Assabet. This allows us to eliminate machine_has_neponset() from this driver, replacing it instead with
