Would be nice if commit message spelled out what PPR is.

FYI, there is no need to add this to POSSIBLE, since you are adding it
to POWER7 anyway.

Will remove CPU_FTR_HAS_PPR for POSSIBLE macro. Added this in second
version for enabling this feature with command parameter, but forgot to
remove it.
