Subject: crypto: twofish - disable AVX2 implementation

It appears that the performance of 'vpgatherdd' is suboptimal for this kind of
workload (tested on Core i5-4570) and causes twofish_avx2 to be significantly
slower than twofish_avx. So disable the AVX2 implementation to avoid
performance regressions.

Subject: crypto: sahara - fix building as module

The sahara crypto driver has an incorrect MODULE_DEVICE_TABLE, which
prevents us from actually building this driver as a loadable module.

sahara_dt_ids is a of_device_id array, so we have to use
MODULE_DEVICE_TABLE(of, ...).
