Convert the Arm MPS2 Timer binding to DT schema format. It's a
straight-forward conversion.

ARM MPS2 timer



The MPS2 platform has simple general-purpose 32 bits timers.



Required properties:

- compatible	: Should be "arm,mps2-timer"

- reg		: Address and length of the register set

- interrupts	: Reference to the timer interrupt



Required clocking property, have to be one of:

- clocks	  : The input clock of the timer

- clock-frequency : The rate in HZ in input of the ARM MPS2 timer



Examples:



timer1: mps2-timer@40000000 {

	compatible = "arm,mps2-timer";

	reg = <0x40000000 0x1000>;

	interrupts = <8>;

	clocks = <&sysclk>;

};



timer2: mps2-timer@40001000 {

	compatible = "arm,mps2-timer";

	reg = <0x40001000 0x1000>;

	interrupts = <9>;

	clock-frequency = <25000000>;

};
