Convert the NXP PCF85063 RTC binding to DT schema format.
Add 'interrupts' and 'wakeup-source' as this device has an interrupt
which was not documented, but is in use.
'clock-output-names' and '#clock-cells' are added as well, those were
probably missed when adding clkout support in commit 8c229ab6048b
("rtc: pcf85063: Add pcf85063 clkout control to common clock framework")

Krzysztof, thanks for your review.
Changes in v2:
* Sorted compatible list
* Mentioned new #clock-cells and clock-output-names properties in commit message
* Removed 'interrupt-names', not needed/used anyway
* Fixed quartz-load-femtofarads defintion/description

-* NXP PCF85063 Real Time Clock
-
-Required properties:
-- compatible: Should one of contain:
- "nxp,pca85073a",
- "nxp,pcf85063",
- "nxp,pcf85063a",
- "nxp,pcf85063tp",
- "microcrystal,rv8263"
-- reg: I2C address for chip.
-
-Optional property:
-- quartz-load-femtofarads: The capacitive load of the quartz(x-tal),
- expressed in femto Farad (fF). Valid values are 7000 and 12500.
- Default value (if no value is specified) is 7000fF.
-
-Optional child node:
-- clock: Provide this if the square wave pin is used as boot-enabled fixed clock.
-
-Example:
-
-pcf85063: rtc@51 {
- compatible = "nxp,pcf85063";
- reg = <0x51>;
- quartz-load-femtofarads = <12500>;
-
- clock {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <32768>;
- };
-};
