ltq-deu: make deu hash lock global and remove md5_hmac_ exports
All hash algorithms use the same base IFX_HASH_CON to access the hash unit. Parallel threads should not be able to call different hash algorithms and therefor a global lock is required. Fixed linker warning, that md5_hmac_init, md5_hmac_update and md5_hmac_final are static export symbols. The export symbols are not required, because the functions are exposed using shash_alg structure. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
