The result can be used for conditional code based on whether device is GP (general purpose), EMU or HS (high security). Also move the type defines so omap1 code compile does not require ifdefs for sections using these defines. This code is needed for the following fix to set the SRAM size correctly for HS omaps. Also at least PM and watchdog code will need this function.
