irqchip/mbigen: Adjust DT bindings to handle multiple devices in a module

A mbigen hardware module can contain more than one device node. These device
nodes contain the same register definition.

mbigen_dev1:intc_dev1 {
	...
	reg = <0x0 0xc0080000 0x0 0x10000>;
	...
};

mbigen_dev2:intc_dev2 {
	...
	reg = <0x0 0xc0080000 0x0 0x10000>;
	...
};

In this case both devices try to request the same resource resulting in a
resource conflict.

To address this problem the devices need to be subnodes of the mbigen hardware
module, which then contains the unique register space.
