-ZTE zx2967 I2C controller

-Required properties:
- - compatible: must be "zte,zx296718-i2c"
- - reg: physical address and length of the device registers
- - interrupts: a single interrupt specifier
- - clocks: clock for the device
- - #address-cells: should be <1>
- - #size-cells: should be <0>
- - clock-frequency: the desired I2C bus clock frequency.
-
-Examples:
-
- i2c@...000 {
- compatible = "zte,zx296718-i2c";
- reg = <0x00112000 0x1000>;
- interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&osc24m>;
- #address-cells = <1>
- #size-cells = <0>;
- clock-frequency = <1600000>;
