crypto: qce - allow building only hashes/ciphers
Allow the user to choose whether to build support for all algorithms
(default), hashes-only, or skciphers-only.
The QCE engine does not appear to scale as well as the CPU to handle
multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the
QCE handles only 2 requests in parallel.
Ipsec throughput seems to improve when disabling either family of
algorithms, sharing the load with the CPU. Enabling skciphers-only
appears to work best.
