Second Timeout Status(SECOND_TO_STS) (second_to_sts): PMC sets this bit to
1 to indicate that the TIMEOUT bit had been (or is currently) set and a second timeout
occurred before the TCO_RLD register was written. If this bit is set and the NO_REBOOT
config bit is 0, then the PMC will reboot the system after the second timeout. The reboot
is done by asserting PMU_PLTRST_B. This bit is only cleared by writing a 1 to this bit or
by a RSMRST_B.
