crypto: vmx - Increase priority of aes-cbc cipher
All of the VMX AES ciphers (AES, AES-CBC and AES-CTR) are set at
priority 1000. Unfortunately this means we never use AES-CBC and
AES-CTR, because the base AES-CBC cipher that is implemented on
top of AES inherits its priority.
To fix this, AES-CBC and AES-CTR have to be a higher priority. Set
them to 2000.
Testing on a POWER8 with:
cryptsetup benchmark --cipher aes --key-size 256
Shows decryption speed increase from 402.4 MB/s to 3069.2 MB/s,
over 7x faster. Thanks to Mike Strosaker for helping me debug
this issue.

crypto: vmx - Fix ABI detection
When calling ppc-xlate.pl, we pass it either linux-ppc64 or
linux-ppc64le. The script however was expecting linux64le, a result
of its OpenSSL origins. This means we aren't obeying the ppc64le
ABIv2 rules.
Fix this by checking for linux-ppc64le.
