crypto/dpaax_sec: enhance GCM descs to not skip AAD
The GCM descriptors needlessly skip auth_only_len bytes from output
buffer. Due to this, workarounds have to be made in dpseci driver code.
Also this leads to failing of one cryptodev test case for gcm. In this
patch, we change the descriptor construction and adjust dpaaX_sec
accordingly. The test_AES_GCM_auth_encrypt_SGL_out_of_place_400B_1seg
now passes.
