Since the ECDH key generation takes a different path, it needs to be
tested as well. For this generate the public debug key from the private
debug key and compare both.
This also moves the seeding of the private key into the SMP calling code
to allow for easier re-use of the ECDH key generation helper.

When generating new ECDH keys with kpp, the shared secret input needs to
be set to NULL. Fix this by including kpp_request_set_input call.

Bluetooth would crash when computing ECDH keys with kpp
if VMAP_STACK is enabled. Fix by allocating data passed
to kpp on heap.

* Convert both smp and selftest to crypto kpp API
* Remove module ecc as no more required
* Add ecdh_helper functions for wrapping kpp async calls
This patch has been tested *only* with selftest, which is called on
module loading.
