Subject: [PATCH v7 005/102] x86/virt/vmx/tdx: export platform_tdx_enabled()

From: Isaku Yamahata <isaku.yamahata@...el.com>

TDX KVM uses platform_tdx_enabled() via vmx_hardware_setup() to check if the
platform supports TDX, concretely CPU SEAM mode, irrespective of TDX module
is loaded or initialized.
