IPCC is fairly core to system, so as such it should never be unloaded. It registers as a mailbox + irq controller and the irq controller drivers in kernel are not supposed to be unloaded as they don't have the visibility over the clients consuming the irqs. Hence adding supress_bind_attrs to disable bind/unbind via sysfs.
