Services the watchdog. This resets the count value to
zero. This may take up to three clk_ilo0 cycle to take
effect. Hardware clears this bit, after necessary
synchronization. To ensure a pending SERVICE write
is reflected, firmware should wait until this bit reads low
before attempting to write SERVICE=1. If WDT is
disabled, SERVICE will not trigger a LOWER_ACTION
and will not clear a preloaded count value.
