crypto: ccp - Remove check for x86 family and model
Each x86 SoC will make use of a unique PCI ID for the CCP device so it is not necessary to check for the CPU family and model. Signed-off-by: Gary R Hook <gary.hook@amd.com> Acked-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
