ipack: split ipack_device_register() in several functions One function is ipack_device_init(). If it fails, the caller should execute ipack_put_device(). The second function is ipack_device_add that only adds the device. If it fails, the caller should execute ipack_put_device(). Then the device is removed with refcount = 0, as device_register() kernel documentation says. ipack_device_del() is added to remove the device.

Staging: ipack: use idr interface for numbering buses Use idr interface to give the bus number. That way, we remove the limitation of 64 buses. The mutex is removed because the ida interface uses spinlocks inside, so it is not needed an extra lock.
