chiptool: patch-out broken svd-parser

Fork repository that contains svd-parser as well as a broken
submodule that causes a Cargo vendor crash in the newer versions of
the Nix rust-platform (since nixpkgs @
5cd869caa4ea1bf1bde71731ecc96b24e1bdcc2d).

Upstream variant contains a patch that fixes this
(rust-embedded/svd#294) and additional features
that do not break chiptool.

Nice plus: new fetchCargoVendor supports git dependencies, we do not
have to use importCargoLock and manually populate git dependencies'
output hashes to source dependencies!
