{chiron,sagit}_defconfig: Use a timer frequency of 100 Hz

The use of high CPU frequencies combined with a large number of cores
makes latency decent with a 100 Hz scheduler tick. Reducing the tick
rate from 300 Hz to 100 Hz improves throughput and significantly reduces
the number of interrupts firing off per second, improving power
consumption.
