Minimal early init - PRCM initialization not yet taken care. Control module is similar (base address, feature register etc.) as that of AM335x, while PRCM base address is different. Instead of adding a new header file for AM43x, PRCM base address is added in AM335x header file as it is similar to it to a large extent.
