arm32: remove memmap_notinit bookkeeping

Removes the bookkeeping of whether memory map has been initialized or
not using the memmap_notinit variable. Memory map is always initialized
before any core_va2pa() or core_pa2va() is performed so the bookkeeping
doesn't do much good.

The variable was updated with caches disabled while other CPUs might have
caches enabled. This can result in unexpected problems.

Add Concat KDF (Concatenation Key Derivation Function, NIST SP 800-56A R1)

Concat KDF is a key derivation algorithm defined in section 5.8.1 of
the NIST Special Publication 800-56A Revision 1, "Recommendation for Pair-Wise
Key Establishment Schemes Using Discrete Logarithm Cryptography"
(http://csrc.nist.gov/publications/nistpubs/800-56A/SP800-56A_Revision1_Mar08-2007.pdf)

This is a TEE implementation of the function, which supports the following
hash algorithms: SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512.
The actual key derivation is implemented in TEE_DeriveKey() thanks to
custom extensions to the GlobalPlatform API v1.0. Please refer to
documentation/extensions/crypto_concat_kdf.md for details.
