Meng Yu 6763f5ea2d crypto: ecdh - move curve_id of ECDH from the key to algorithm name
1. crypto and crypto/atmel-ecc:
   Move curve id of ECDH from the key into the algorithm name instead
   in crypto and atmel-ecc, so ECDH algorithm name change form 'ecdh'
   to 'ecdh-nist-pxxx', and we cannot use 'curve_id' in 'struct ecdh';
2. crypto/testmgr and net/bluetooth:
   Modify 'testmgr.c', 'testmgr.h' and 'net/bluetooth' to adapt
   the modification.
