Counter vs Btimer for tmtests

[Joel Sherrill]

Thanks.

A ticket needs to be filed to convert the tests if the counter works on all
BSPs.
What are the BSP requirements for counter?

Also, it likely means that results need to be recalibrated and cannot be
compared
for historical purposes.

At this point, I consider the two tests using counter future looking and
outliers.
