dt-binding: pcf8523: add xtal load capacitance
The NXP pcf8523 supports two different xtal load capacitance
- 7000fF (7pF) HW default
- 12500fF (12.5pF) Minimum power consumption, driver default
To obtain a precise RTC the pcf8523 must be configured
with the correct capacitance load of the xtal.
Add a property to specify the xtal capacitance load.
The default value matches that of the current Linux driver.
With a dedicated binding remove the entry in rtc.txt
