The mux code manages the pad core and pad wakeup related base address inside the mux framework. For other usage only control core and control pad bases are necessary. So this patch maps only needed pad control base address which is used by device drivers and infrastructure code The main control core base is still kept same in this patch to keep git-bisect working. This will be fixed in the relevant patch in this series.
