Subject: [PATCH 47/52] uadk/v1: fix for sec cipher bd1 ci_gen configuration

In storage scenarios, the XTS mode is used for encrypting and decrypting
data on and off disks. According to the definition of this mode, the input
parameter to genarate IV is the LBA, so update SEC bd1 xts mode CI_GEN
from 0 to 3, which means use LBA mode.
