irqchip/mbigen: Don't use bus_get_dev_root() to find the parent
bus_get_dev_root() returns sp->dev_root which is set in subsys_register(),
but subsys_register() is not called by platform_bus_init().
Therefor for the platform_bus_type, bus_get_dev_root() always returns NULL.
This makes mbigen_of_create_domain() always return -ENODEV.
Don't try to retrieve the parent via bus_get_dev_root() and
unconditionally hand a NULL pointer to of_platform_device_create() to
fix this.
Fixes: fea087fc291b ("irqchip/mbigen: move to use bus_get_dev_root()")
