From: Harsh Prateek Bora <harshpb@linux.ibm.com>
Power9/10 initialization code consists of a lot of logical OR of
various flag bits as supported by respective Power platform during its
initialization, most of which is duplicated and only selected bits are
added or removed as needed with each new platform support being added.
Remove the duplicate code and share using common macros.
