PDCP control plane can support 5 bit and 12 bit
sequence number. This patch add test cases and test
vectors for all supported algo combinations of cipher+integrity
(NULL+NULL, NULL+AES, NULL+SNOW, NULL+ZUC,
 AES+NULL,  AES+SNOW, AES+AES,   AES+ZUC,
 SNOW+NULL, SNOW+AES, SNOW+SNOW, SNOW+ZUC,
 ZUC+NULL,  ZUC+AES,  ZUC+SNOW,  ZUC+ZUC).

The test cases are added in DPAA_SEC and DPAA2_SEC
