[PATCH] powerpc/ep8248e: Mark driver as non removable

[Uwe Kleine-König]

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.
