dt-bindings: rtc: ds3231: Remove text binding

Browse Source 
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>;
...
};
