Re: [PATCH v3 3/7] dt-bindings: interrupt-controller: Convert mti,gic to DT schema

Modern device tree bindings are supposed to be created as YAML-files
in accordance with DT schema. This commit replaces MIPS GIC legacy bare
text binding with YAML file. As before the binding file states that the
corresponding dts node is supposed to be compatible with MIPS Global
Interrupt Controller indicated by the "mti,gic" compatible string and
to provide a mandatory interrupt-controller and '#interrupt-cells'
properties. There might be optional registers memory range,
"mti,reserved-cpu-vectors" and "mti,reserved-ipi-vectors" properties
specified.

MIPS GIC also includes a free-running global timer, per-CPU count/compare
timers, and a watchdog. Since currently the GIC Timer is only supported the
DT schema expects an IRQ and clock-phandler charged timer sub-node with
"mti,mips-gic-timer" compatible string.

I don't really know who is the corresponding driver maintainer, so I
added Paul to the maintainers property since he used to be looking for the
MIPS arch and Thomas looking after it now. Any idea what email should be
specified there instead?

Changelog v3:
- Since timer sub-node has no unit-address, the node shouldn't be named
  with one. So alter the MIPS GIC bindings to have a pure "timer"
  sub-node.
- Discard allOf: [ $ref: /schemas/interrupt-controller.yaml# ].
- Since it's a conversion patch use GPL-2.0-only SPDX header.
