Felipe Moura da0b519204 netutils/dropbear: back chacha20-poly1305 with NuttX /dev/crypto 
Replace the bundled libtomcrypt chacha20-poly1305 implementation with an
adapter that drives the NuttX crypto device: the SSH construction maps onto
CRYPTO_CHACHA20_DJB (the original 64-bit counter/nonce ChaCha20
parameterization used by chacha20-poly1305@openssh.com) for the packet
length and payload streams, and onto CRYPTO_POLY1305 for the authentication
tag (plain MACs are driven in two steps through /dev/crypto: COP_FLAG_UPDATE
feeds the data, a final call retrieves the tag).
