[PATCH v5 04/10] dt-bindings: irqchip: ti, sci-intr: Update bindings to drop the usage of gic as parent

[Lokesh Vutla]

Drop the firmware related dt-bindings and use the hardware specified
interrupt numbers within Interrupt Router. This ensures interrupt router
DT node need not assume any interrupt parent type.
