[PATCH v2] spmi: pmic-arb: Pass the correct of_node to irq_domain_add_tree

[Konrad Dybcio]

Currently, irqchips for all of the subnodes (which represent a given
bus master) point to the parent wrapper node. This is no bueno, as
no interrupts arrive, ever (because nothing references that node).

Fix that by passing a reference to the respective master's of_node.

Worth noting, this is a NOP for devices with only a single master
described.
