MLECO-3096: Removing "timer" from HAL profile.
Attempting to have timer functionality contained within
the platform drivers "package" as it should (in line with
the refactoring work done so far under HAL). This will
ensure that we don't need two timer implementations under
HAL "profiles" and therefore, this whole directory can be
removed.
This change also addressed issue with the applicatio level
Profiler code knowing about how the PMU has been set up by
the platform code. This link has been removed completely.
This will make it much easier to add/amend the Ethos-U PMU
event counters types and give each platform the capability
of populating their relvant counters. The application level
Profiler doesn't know which metrics it is displaying but
just calculates and maintains statistics for whatever PMU
counters it receives from the HAL level.
A fix for timing adapter issue introduced in the last CR
is also included.
