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
