From: Suraj Jitindar Singh <sjitindarsingh@gmail.com>

In default_caps_with_cpu() we set spapr_cap_cfpc to broken for POWER8
processors and before.

Since we no longer require private l1d cache on POWER8 for this cap to
be set to workaround change this to default to broken for POWER7
processors and before.
