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: ee13cb249fab ("powerpc/64s: Add support for software count cache flush")
