[SRU][N][PATCH v5 1/2] selftests/powerpc: Lower run time of count_stcx_fail test

[Zixing Liu]

From: Michael Ellerman <mpe at ellerman.id.au>

BugLink: https://bugs.launchpad.net/bugs/2141536

The count_stcx_fail test runs for close to or just over 2 minutes, which
means it sometimes times out.

That's overkill for a test that just demonstrates some PMU counters
are working. Drop the 64 billion instruction case, to lower the runtime
to ~30s.
