powerpc/fsl: Fix spectre_v2 mitigations reporting

Currently for CONFIG_PPC_FSL_BOOK3E the spectre_v2 file is incorrect:

  $ cat /sys/devices/system/cpu/vulnerabilities/spectre_v2
  "Mitigation: Software count cache flush"

Which is wrong. Fix it to report vulnerable for now.

Fixes: 0896e37d6a18 ("powerpc/64s: Add support for software count cache flush")
