Update lowrisc_ibex to lowRISC/ibex@6b9165f

Update code from upstream repository
https://github.com/lowRISC/ibex.git to revision
6b9165fa66b49534226acfcb739f2c252be4853c

* [doc] Update READMEs with best CoreMark results (Greg Chadwick)
* [sw] Enable choice of -march= string for CoreMark (Greg Chadwick)
* Value passed to UVM set_timeout is calculated as 1000000000 basing
  on 1ns/1ps timescale. But if you are using precompiled UVM it may be
  compiled with other timescale depending on compilation option used
  when it was compiled or tools default timescale value (uvm does not
  set timescale int the code). In this case for us precompiled UVM
  timescale is 1ps/1ps - so UVM gets 1000000000 in set timeout but
  interprets it as ps. As a result timeout is 1000 times smaller that
  you expect. That is why we are getting timeouts. It is hard to find
  perfect solution. One of them is to recompile the UVM with
  -timescale 1ns/ps (or whatever you will use for your design). (Dawid
  Zimonczyk)
