Implement reading of the battery voltage low signal for rtc-pcf8523.
The bit is read-only and cannot be cleared by software, so no
clear function is implemented.

Add an RTC driver for PCF8523 chips by NXP Semiconductors. No support is
currently provided for the alarm and interrupt functions. Only the time
and date functionality is implemented.
