dt-bindings: irqchip: ti, sci-inta: Update docs to support different parent.

Browse source 
Drop the firmware related interrupt ranges and use the hardware specified
interrupt numbers within Interrupt Aggregator. This ensures interrupt
aggregator DT node need not assume any interrupt parent type.

- msi-controller: Identifies the node as an MSI controller.
- interrupt-parent: phandle of irq parent.
- ti,sci: Phandle to TI-SCI compatible System controller node.
- ti,sci-dev-id: TISCI device ID of the Interrupt Aggregator.
- ti,sci-rm-range-vint: Array of TISCI subtype ids representing vints(inta
outputs) range within this INTA, assigned to the
requesting host context.
- ti,sci-rm-range-global-event: Array of TISCI subtype ids representing the
global events range reaching this IA and are assigned
to the requesting host context.
- ti,sci-dev-id: TISCI device id of interrupt controller.
- ti,interrupt-ranges: Set of triplets containing ranges that convert
the INTA output interrupt numbers to parent's
interrupt number. Each triplet has following entries:
- First entry specifies the base for vint
- Second entry specifies the base for parent irqs
- Third entry specifies the limit
