The IBM Akebono board uses the PPC476GTR SoC which has a OHCI
compliant USB host interface. This patch adds support for it to the
OHCI platform driver.

As we use device tree to pass platform specific data instead of
platform data we remove the check for platform data and instead
provide reasonable defaults if no platform data is present. This is
similar to what is currently done in ehci-platform.c.
