Cleanup U-Boot boot messages on ARM.

Browse Source 
To match the U-Boot user interface on ARM platforms to the U-Boot
standard (as on PPC platforms), some messages with debug character
are removed from the default U-Boot build.
Enable DEBUG for lib_arm/board.c to enable debug messages.
New CONFIG_DISPLAY_CPUINFO and CONFIG_DISPLAY_BOARDINFO options.
