[PATCH v4 9/9] target/ppc: reduce duplicate code between init_proc_POWER{9, 10}

[Harsh Prateek Bora <harshpb@linux.ibm.com>]

Historically, the registration of sprs have been inherited alongwith
every new Power arch support being added leading to a lot of code
duplication. It's time to do necessary cleanups now to avoid further
duplication with newer arch support being added.
