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 8c229ab604
("rtc: pcf85063: Add pcf85063 clkout control to common clock framework")
