lynxpoint: PMIR register rename 

The register that controls global reset is named the Power
Mangement Initialization Regiser (PMIR). Update the defines
to reflect the documentation.

Additionally, there is no core well reset control according to the
EDS. There is, however, a CF9 lock field to lock this register down.
