[U-Boot] [PATCH v3 12/15] ARM: omap-common: Add device type to CPU string

[Daniel Allred]

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.

V3:
 Rebase on current master

V2:
 Move device type defines to omap_common.h, remove duplicates
