The PCA85073A RTC has the same programming model as the PCF85063A.
Add a compatible entry for it.
Tested on a custom i.MX6SX based board.

The RZN1 RTC can compensate the imprecision of the oscillator up to
approximately 190ppm.
Seconds can last slightly shorter or longer depending on the
configuration.
Below ~65ppm of correction, we can change the time spent in a second
every minute, which is the most accurate compensation that the RTC can
offer. Above, the compensation will be active every 20s.

The RZN1 RTC can trigger an interrupt when reaching a particular date up
to 7 days ahead. Bring support for this alarm.
One drawback though, the granularity is about a minute.

Add a basic RTC driver for the RZ/N1.
