Subject: ppc/spapr_caps: Don't disable cap_cfpc on POWER8 by default

Git-commit: b2540203bdf4a390c3489146eae82ce237303653
References: bsc#1174374

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.
