Interrupt line is shared between global and all context faults for each SMMU instance.
Nvidia implementation checks for both Global and context faults on each interrupt to an SMMU instance.
It can be either 1 or 3. If we make it 3, we need to add two more irq entries in node for context faults.
In the future, we can update arm-smmu.c to support shared interrupt line between global and all context faults.
