HKDF, as defined by RFC5869, is a simple (HMAC)-based key derivation function, which can be used as a building block in various protocols and applications.

A PR for the existing HKDF in MCUBoot was added here:
intel/tinycrypt#43

Once this is merged, this PR should remove the local implementation and
switch to using the one provided by Tinycrypt.

HKDF support in tinycrypt is not integrated into the master branch
so intel/tinycrypt#43 must be included.
