Suggestion: this and the repo_url_* / path_* values could be moved into
a function like so:
set_params() {
case "$1" in
mbedtls)
path=lib/mbedtls/external/mbedtls
repo_url=https://github.com/Mbed-TLS/mbedtls.git
;;
... other cases here ...
*)
echo "Invalid subtree name: $subtree_name"
print_usage
exit 1
esac
}
set_params $1

Overall LGTM. FWIW:
