Kirill A. Shutemov 564ea84c8c x86/tdx: Dump attributes and TD_CTLS on boot
Dump TD configuration on boot. Attributes and TD_CTLS define TD
behavior. This information is useful for tracking down bugs.

The output ends up looking like this in practice:

[    0.000000] tdx: Guest detected
[    0.000000] tdx: Attributes: SEPT_VE_DISABLE
[    0.000000] tdx: TD_CTLS: PENDING_VE_DISABLE ENUM_TOPOLOGY VIRT_CPUID2 REDUCE_VE
