This patch fixes a problem with the month being read and written
incorrectly (offset by one). This only gets visible by also using
the Linux driver (rtc-m41t80).
Tested on AMCC Canyonlands.

Modify the RTC API to provide one a status for the time reported by
the rtc_get() function:
0 - a reliable time is guaranteed,
< 0 - a reliable time isn't guaranteed (power fault, clock issues,
and so on).
The RTC chip drivers are responsible for providing this info if the
corresponding chip supports such functionality. If not - always
report that the time is reliable.
The POST RTC test was modified to detect the RTC faults utilizing
this new rtc_get() feature.
