scripts: move hash function from scripts/kconfig/ to scripts/include/
This function was originally added by commit 8af27e1dc4e4 ("fixdep: use hash table instead of a single array"). Move it to scripts/include/ so that other host programs can use it. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
