Convert the NXP I2C controller for LPC2xxx/178x/18xx/43xx to newer DT schema. Created DT schema based on the .txt file which had `compatible`, `reg`, `interrupts`, `clocks`, `#address-cells` and `#size-cells` as required properties. Additional changes to the original .txt binding - added maintainer from the MAINTAINERS file. - added resets property required by the corresponding DTS files.
