Updated the patch with the suggestions by Gedare.
Tests on real hardware yield the same frequency results
as returned by FreeBSD on the same hardware.
Also, subsequent calibrations only differ by <1 kHz.

I would like to backport this fix to RTEMS5.
The corresponding ticket is here: https://devel.rtems.org/ticket/4456

Best regards,
