Well point taken, but the PCF50633 interrupt in the GTA02 case at least
is itself an EINT driver.  I looked in the PMU datasheet and you can
trigger the device interrupt from its RTC alarm.  So no problem that we
use an RTC from another chip: we can still sleep properly and wake at a
given time.

Dunno anything about this.  But for GTA02, we can reasonably assume they
have current firmware.
