powerpc/ep8248e: Mark driver as non removable

Browse Source 
Instead of resorting to BUG() ensure that the driver isn't unbound by
suppressing its bind and unbind sysfs attributes. As the driver is
built-in there is no way to remove a device once bound.

As a nice side effect this allows to drop the remove function.
