Borislav Petkov (AMD) 0ecaefb303 x86/CPU/AMD: Track SNP host status with cc_platform_*() 
The host SNP worthiness can determined later, after alternatives have
been patched, in snp_rmptable_init() depending on cmdline options like
iommu=pt which is incompatible with SNP, for example.

Which means that one cannot use X86_FEATURE_SEV_SNP and will need to
have a special flag for that control.

Use that newly added CC_ATTR_HOST_SEV_SNP in the appropriate places.

Move kdump_sev_callback() to its rightful place, while at it.

Fixes: 216d106c7f ("x86/sev: Add SEV-SNP host initialization support")
