crypto: octeontx2 - Fix address alignment issue on ucode loading

Browse source

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:
  "9382bc44b5 arm64: allow kmalloc() caches aligned to the
   smaller cache_line_size()"

Completion address should be 32-Byte alignment when loading
microcode.
