John Garry e0257a01d6 perf pmu: Fix alias events list 
Commit 0e0ae87422 ("perf list: Display hybrid PMU events with cpu
type") changes the event list for uncore PMUs or arm64 heterogeneous CPU
systems, such that duplicate aliases are incorrectly listed per PMU
(which they should not be), like:

  # perf list
  ...
  unc_cbo_cache_lookup.any_es
  [Unit: uncore_cbox L3 Lookup any request that access cache and found
  line in E or S-state]
  unc_cbo_cache_lookup.any_es
  [Unit: uncore_cbox L3 Lookup any request that access cache and found
  line in E or S-state]
  unc_cbo_cache_lookup.any_i
  [Unit: uncore_cbox L3 Lookup any request that access cache and found
  line in I-state]
  unc_cbo_cache_lookup.any_i
  [Unit: uncore_cbox L3 Lookup any request that access cache and found
  line in I-state]
  ...

Notice how the events are listed twice.

The named commit changed how we remove duplicate events, in that events
for different PMUs are not treated as duplicates. I suppose this is to
handle how "Each hybrid pmu event has been assigned with a pmu name".

Fix PMU alias listing by restoring behaviour to remove duplicates for
non-hybrid PMUs.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
