Update the CPU string output so that the device type is now included as part of the CPU string that is printed as the SPL or u-boot comes up. This update adds a suffix of the form "-GP" or "-HS" for production devices, so that general purpose (GP) and high security (HS) can be distiguished. Applies to all OMAP5 variants.
