Hi,

this Series increases the timer frequency and decreases min_delta_ns.
I saw pretty high max latencies with cyclictest: ~600us.

The cause was the min_delta_ns value of 0xf 32kHz clockcycles.
But with the 32kHz Clock, the period is still around 30us.
So we just increase the clock freqeuncy driving the timers
here.
