crypto: octeontx2 - Fix address alignment on CN10K A0/A1 and OcteonTX2

octeontx2 crypto driver allocates memory using kmalloc/kzalloc,
and uses this memory for dma (does dma_map_single()). It assumes
that kmalloc/kzalloc will return 128-byte aligned address. But
kmalloc/kzalloc returns 8-byte aligned address after below changes:
  "9382bc44 arm64: allow kmalloc() caches aligned to the
   smaller cache_line_size()

Memory allocated are used for following purpose:
 - Input data or scatter list address - 8-Byte alignment
 - Output data or gather list address - 8-Byte alignment
 - Completion address - 32-Byte alignment.

This patch ensures all addresses are aligned as mentioned above.
