Migrate mediatek,cirq.txt to dt schema as mediatek,mtk-cirq.yaml.
While at it, I've also fixed some typos that were present in the
original txt binding, as it was suggesting that the compatible
string would have "mediatek,cirq" as compatible but, in reality,
that's supposed to be "mediatek,mtk-cirq" instead.
Little rewording on property descriptions also happened for
them to be more concise.

-* Mediatek 27xx cirq
-
-In Mediatek SOCs, the CIRQ is a low power interrupt controller designed to
-work outside MCUSYS which comprises with Cortex-Ax cores,CCI and GIC.
-The external interrupts (outside MCUSYS) will feed through CIRQ and connect
-to GIC in MCUSYS. When CIRQ is enabled, it will record the edge-sensitive
-interrupts and generate a pulse signal to parent interrupt controller when
-flush command is executed. With CIRQ, MCUSYS can be completely turned off
-to improve the system power consumption without losing interrupts.
-
-Required properties:
-- compatible: should be one of
- - "mediatek,mt2701-cirq" for mt2701 CIRQ
- - "mediatek,mt8135-cirq" for mt8135 CIRQ
- - "mediatek,mt8173-cirq" for mt8173 CIRQ
- and "mediatek,cirq" as a fallback.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Use the same format as specified by GIC in arm,gic.txt.
-- reg: Physical base address of the cirq registers and length of memory
- mapped region.
-- mediatek,ext-irq-range: Identifies external irq number range in different
- SOCs.
-
-Example:
- cirq: interrupt-controller@10204000 {
- compatible = "mediatek,mt2701-cirq",
- "mediatek,mtk-cirq";
- interrupt-controller;
- #interrupt-cells = <3>;
- interrupt-parent = <&sysirq>;
- reg = <0 0x10204000 0 0x400>;
- mediatek,ext-irq-start = <32 200>;
- };
