For the _CPU_Counter_difference() please use

You need also a call to rtems_counter_initialize_converter() with the right
frequency.
Is this used for _CPU_Counter_read (160 MHz in our case) or for
benchmark_timer_read (1 MHz in our case now).
It is used rtems_counter_delay_nanoseconds() function which uses
_CPU_Counter_read().
Or should we use
_CPU_Counter_read for benchmark_timer_read to unify these?
It is possible to write a benchmark timer which uses the CPU counter and works
for all BSPs. I simply had no time yet to do this.
