powerpc/platforms/83xx/suspend: Prevent unloading the driver
Returning an error in .remove() doesn't prevent a driver from being
unloaded. On unbind this only results in an error message, but the
device is remove anyhow.
I guess the author's idea of just returning -EPERM in .remove() was to
prevent unbinding a device. To achieve that set the suppress_bind_attrs
driver property and drop the useless .remove callback.
This is a preparation for making platform remove callbacks return void.
