Add the parameters for the NIST P384 curve and define a new curve ID
for it. Make the curve available in ecc_get_curve.
Summary of changes:
* crypto/ecc_curve_defs.h
- add nist_p384 params
* include/crypto/ecdh.h
- add ECC_CURVE_NIST_P384
* crypto/ecc.c
- change ecc_get_curve to accept nist_p384

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.

Add the KPP API documentation to the kernel crypto API Sphinx
documentation. This addition includes the documentation of the
ECDH and DH helpers which are needed to create the approrpiate input
data for the crypto_kpp_set_secret function.
