treewide: drop outdated compiler version remarks in Kconfig help texts

As of writing, Documentation/Changes states the minimal versions of GNU C
being 8.1, Clang being 15.0.0 and binutils being 2.30.  A few Kconfig help
texts are pointing out that specific GCC and Clang versions are needed,
but by now, those pointers to versions, such later than 4.0, later than
4.4, or clang later than 5.0, are obsolete and unlikely to be found by
users configuring their kernel builds anyway.

Drop these outdated remarks in Kconfig help texts referring to older
compiler and binutils versions.  No functional change.

          Any architecture with load-and-swap or store-and-swap
          instructions should set this. And it shouldn't hurt to set it
