powerpc: Remove check of ibm,smt-snooze-delay OF property
powerpc: Remove check of ibm,smt-snooze-delay OF property

I'm not sure why we have code for parsing an ibm,smt-snooze-delay OF
property. Since we have a smt-snooze-delay= boot option and we can
also set it at runtime via sysfs, it should be safe to get rid of
this code.
