crypto: axis - give DMA the start of the status buffer
The driver was optimized to only do cache maintenance for the last
word of the dma descriptor status array. Unfortunately an omission
also passed the last word as the address of the array start to the DMA
engine. In most cases this goes unnoticed since the hardware aligns
the address to a 64 byte boundary.
