Add support for parsing the parameters of a NIST P256 or NIST P192 key.
Enable signature verification using these keys. The new module is
enabled with CONFIG_ECDSA:
  Elliptic Curve Digital Signature Algorithm (NIST P192, P256 etc.)
  is A NIST cryptographic standard algorithm. Only signature verification
  is implemented.

Great, ECDSA has been lacking for a way too long. Just wanted to
acknowledge support for this, I just now also skimmed the change
from patchwrok (way too quickly for reviewed-by but well enough
for ack).
