Commit 17176c2e2b adds a test of a new RTC
register flag to distinguish a system reset and a wake up event. Shame on me,
I have forgotten to define the newly used flag yet.
While already here, I also try to document the other flags the RTC provides.

When the built-in RTC in the i.MX28 is programmed to wake-up the SoC, the RTC
reports two events: RST and WAKE. RST is okay in this case, because the PMIC
was really powered down. But the real event is the WAKE from the RTC and
should have precedence over the RST event. So, report the WAKE event for this
special case.
