CI: Increase number of test trials for timing tests
- Increasing a number of test trials aims to reduce variations and
improve reliability of the
nr_ulsimandnr_dlsimtest results. - Disable CPU sleep states on the machine when running physims.
- Minor adjustment of timing threshold in 60 MHz phytest.
All modification in this MR are related to CI confs of
RAN-gNB-N300-Timing-Phytest-LDPC pipeline, so I selected
documentation label and I will trigger the test manually.
