Convert the m41t80 text schema to YAML schema.
Add "#clock-cells" requirement, which is required by clock-output-names.

V2: - Add maxItems:1 to clock-output-names
- Skip wakeup-source property, comes from rtc.yaml
- Mention the new clock-cells requirement coming from
clock-output-names property.
- Rename rtc-m41t80.txt to st,m41t80.yaml

-ST M41T80 family of RTC and compatible
-
-Required properties:
-- compatible: should be one of:
- "st,m41t62",
- "st,m41t65",
- "st,m41t80",
- "st,m41t81",
- "st,m41t81s",
- "st,m41t82",
- "st,m41t83",
- "st,m41t84",
- "st,m41t85",
- "st,m41t87",
- "microcrystal,rv4162",
-- reg: I2C bus address of the device
-
-Optional properties:
-- interrupts: rtc alarm interrupt.
-- clock-output-names: From common clock binding to override the default output
- clock name
-- wakeup-source: Enables wake up of host system on alarm
-
-Optional child node:
-- clock: Provide this if the square wave pin is used as boot-enabled fixed clock.
-
-Example:
- rtc@68 {
- compatible = "st,m41t80";
- reg = <0x68>;
- interrupt-parent = <&UIC0>;
- interrupts = <0x9 0x8>;
-
- clock {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <32768>;
- };
- };
