To keep fork as closely synced with upstream, move NSS packages back into repository. Not sure why they were moved out from my original fork. * nss-firmware * qca-nss-crypto * qca-nss-cfi Removed the following: * mhz (already available in packages repo) * qrtr (unecessary, and has been broken for years) Also moved packages out of `qca` and back into root directory.
