The RTC generic bindings has a bunch of devices that have a pretty simple
binding, with just compatible, reg and optional interrupts properties.
This is exactly what the trivial devices YAML schema has been created for,
except that they can also have the start-year property, but not any other
generic RTC property.
Let's create a schema with those constraints.

The Epson rx8571 is compatible with the Epson rx8581 RTC.
The difference between the rx8571 and rx8581 RTC is that the former has
16 bytes more RAM. This renders them incompatible from a DT point of view.

Add a driver for the MicroCrystal RV-3028. It is a SMT Real-Time Clock
Module that incorporates an integrated CMOS circuit together with an XTAL.
It has an i2c interface.
The driver handles date/time, alarms, trickle charging, timestamping,
frequency offset correction, EEPROM and NVRAM.

The NXP pcf85063 supports two different xtal load capacitance
- 7000fF (7pF) HW default, Linux driver default
- 12500fF (12.5pF) Minimum power consumption
To obtain a precise RTC the pcf85063 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
