crypto: atmel - Use unregister_{aeads,ahashes,skciphers}

Replace multiple for loops with calls to crypto_unregister_aeads(),
crypto_unregister_ahashes(), and crypto_unregister_skciphers().

Remove the definition of atmel_tdes_unregister_algs() because it is
equivalent to calling crypto_unregister_skciphers() directly, and the
function parameter 'struct atmel_tdes_dev *' is unused anyway.
