Make the simple-pm-bus driver probe the Layerscape SCFG dt nodes and
populate platform_device from its child dt nodes.

This is now needed because its child interrupt-controller - ls-extirq -
is being handled as a platform_device instead of being initialized
through the IRQCHIP_DECLARE infrastructure.

Fixes: 1b1f04d8271e ("of/irq: Ignore interrupt parent for nodes without interrupts")
