The crypto API's support for alignmasks for ahash algorithms is nearly useless, as its only effect is to cause the API to align the key and result buffers. The drivers that happen to be specifying an alignmask for ahash rarely actually need it. When they do, it's easily fixable, especially considering that these buffers cannot be used for DMA. In preparation for removing alignmask support from ahash, this patch makes the artpec6 driver no longer use it. This driver is unusual in that it DMAs the digest directly to the result buffer. This is broken because the crypto API provides the result buffer as an arbitrary virtual address, which might not be valid for DMA, even after the crypto API applies the alignmask. Maybe the alignmask (which this driver set only to 3) made this code work in a few more cases than it otherwise would have. But even if so, it doesn't make sense for this single driver that is broken anyway to block removal of the alignmask support.
