Convert the binding documentation for i2c-mt65xx driver to the
YAML schema format.

* write compatibles in a more compact way
* set the node pattern to be "^i2c@[0-9a-f]+$" instead of
"^i2c[0-9]*@[0-9a-f]+"$

-* MediaTek's I2C controller
-
-The MediaTek's I2C controller is used to interface with I2C devices.
-
-Required properties:
- - compatible: value should be either of the following.
- "mediatek,mt2701-i2c", "mediatek,mt6577-i2c": for MediaTek MT2701
- "mediatek,mt2712-i2c": for MediaTek MT2712
- "mediatek,mt6577-i2c": for MediaTek MT6577
- "mediatek,mt6589-i2c": for MediaTek MT6589
- "mediatek,mt6797-i2c", "mediatek,mt6577-i2c": for MediaTek MT6797
- "mediatek,mt7622-i2c": for MediaTek MT7622
- "mediatek,mt7623-i2c", "mediatek,mt6577-i2c": for MediaTek MT7623
- "mediatek,mt7629-i2c", "mediatek,mt2712-i2c": for MediaTek MT7629
- "mediatek,mt8173-i2c": for MediaTek MT8173
- "mediatek,mt8183-i2c": for MediaTek MT8183
- "mediatek,mt8192-i2c": for MediaTek MT8192
- "mediatek,mt8516-i2c", "mediatek,mt2712-i2c": for MediaTek MT8516
- - reg: physical base address of the controller and dma base, length of memory
- mapped region.
- - interrupts: interrupt number to the cpu.
- - clock-div: the fixed value for frequency divider of clock source in i2c
- module. Each IC may be different.
- - clocks: clock name from clock manager
- - clock-names: Must include "main" and "dma", "arb" is for multi-master that
- one bus has more than two i2c controllers, if enable have-pmic need include
- "pmic" extra.
-
-Optional properties:
- - clock-frequency: Frequency in Hz of the bus when transfer, the default value
- is 100000.
- - mediatek,have-pmic: platform can control i2c form special pmic side.
- Only mt6589 and mt8135 support this feature.
- - mediatek,use-push-pull: IO config use push-pull mode.
-
-Example:
-
- i2c0: i2c@1100d000 {
- compatible = "mediatek,mt6577-i2c";
- reg = <0x1100d000 0x70>,
- <0x11000300 0x80>;
- interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_LOW>;
- clock-frequency = <400000>;
- mediatek,have-pmic;
- clock-div = <16>;
- clocks = <&i2c0_ck>, <&ap_dma_ck>;
- clock-names = "main", "dma";
