kconfig: print the range of integer/hex symbol in help text
Without this patch, one has to refer to the Kconfig file to find out the range of an integer/hex symbol. │ Symbol: NR_CPUS [=4] │ Type : integer │ Range : [2 8] │ Prompt: Maximum number of CPUs │ Defined at arch/x86/Kconfig:761 │ Depends on: SMP [=y] && !MAXSMP [=n] │ Location: │ -> Processor type and features Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
