dt-bindings: rtc: ds3231: Remove text binding 



The "maxim,ds3231" compatible is described in the rtc-ds1307.yaml, so
there is no need to keep the text bindings version.

Remove the maxim,ds3231.txt file in favor of the rtc-ds1307.yaml binding.

* Maxim DS3231 Real Time Clock



Required properties:

- compatible: Should contain "maxim,ds3231".

- reg: I2C address for chip.



Optional property:

- #clock-cells: Should be 1.

- clock-output-names:

  overwrite the default clock names "ds3231_clk_sqw" and "ds3231_clk_32khz".



Each clock is assigned an identifier and client nodes can use this identifier

to specify the clock which they consume. Following indices are allowed:

    - 0: square-wave output on the SQW pin

    - 1: square-wave output on the 32kHz pin



- interrupts: rtc alarm/event interrupt. When this property is selected,

  clock on the SQW pin cannot be used.



Example:



ds3231: ds3231@51 {

	compatible = "maxim,ds3231";

	reg = <0x68>;

	#clock-cells = <1>;

};



device1 {

...

	clocks = <&ds3231 0>;

...

};



device2 {

...

	clocks = <&ds3231 1>;

...

};
