Bhadram Varka c4a75f03ac nvethernet: Add support for VM interrupts ...

Adds VM interrupt handling for VM interrupt
based MAC controllers.

Need to pass below parameters from DT -
o Number of VM IRQ's assigned per OS/VM.
o Number of VM channels assigned to a VM IRQ.
o List of DMA channels assigned to a VM IRQ.

Below is the sample DT representation -

vm_irq_config: vm-irq-config {
	nvidia,num-vm-irqs = <4>;
	vm_irq1 {
		nvidia,num-vm-channels = <2>;
		nvidia,vm-channels = <0 1>;
	};
	vm_irq2 {
		nvidia,num-vm-channels = <2>;
		nvidia,vm-channels = <2 3>;
	};
	vm_irq3 {
		nvidia,num-vm-channels = <2>;
		nvidia,vm-channels = <4 5>;
	};
	vm_irq4 {
		nvidia,num-vm-channels = <2>;
		nvidia,vm-channels = <6 7>;
	};
};

ethernet@<base_addr> {
	[...]
	nvidia,vm-irq-config = <&vm_irq_config>;
	[...]
}
