powerpc/crypto: add compression support to arch vec
This patch enables compression engine support in the architecture vector. This causes the Power hypervisor to allow access to the nx comrpession accelerator. Signed-off-by: Seth Jennings <sjenning@linux.vnet.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
