Marek Vasut 699e831e15 ARM: rmobile: Contain CONFIG_ARCH_RMOBILE_BOARD_STRING 
Pull the symbol from the boards and zap struct rmobile_sysinfo as they
are rather useless. The entire purpose of that whole machinery was to
print board name in the CONFIG_ARCH_RMOBILE_BOARD_STRING. Do that in a
far simpler and more contained manner.
