Secondary RTC Reset
When the RTC battery is removed, this jumper resets the
manageability register bits in the RTC.
Note:
1. The SRTCRST# input must always be high when all other
RTC power planes are on.
2. In the case where the RTC battery is dead or missing on
the platform, the SRTCRST# pin must rise before the
RSMRST# pin.
