kernel: limit crypto-hw-ccp to the x86

CRYPTO_DEV_CCP depends on X86 or ARM64
CRYPTO_DEV_CCP_DD depends on CPU_SUP_AMD or ARM64

Compiling this driver makes sense for x86 mainly. If one day support for
ARM64 board with AMD Secure Processor gets added this package may be
updated.

Trying to build this package on bcm4908 was causing:
ERROR: module 'build_dir/target-aarch64_cortex-a53_musl/linux-bcm4908_generic/linux-5.4.110/drivers/crypto/ccp/ccp-crypto.ko' is missing.
