irqchip/mbigen: Don't use bus_get_dev_root() to find the parent
commit fb33a46 upstream. 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.
