Breno Leitao 78f4e2fea0 powerpc64/powernv: re-read RTC after polling 
If OPAL_RTC_READ is busy and does not return the information on the first run,
as returning OPAL_BUSY_EVENT, the system will crash since ymd and hmsm variable
will contain junk values.

This is happening because we were not calling OPAL_RTC_READ again after
OPAL_POLL_EVENTS' return, which would finally replace the old/junk hmsm and ymd
values.

The code was also mixing OPAL_RTC_READ and OPAL_POLL_EVENTS return values.

This patch fix this logic and guarantee that we call OPAL_RTC_READ after
OPAL_POLL_EVENTS return, and guarantee the code will only proceed if
OPAL_RTC_READ returns OPAL_SUCCESS.
