TDX module updates require userspace to select the appropriate module to load. Expose necessary information to facilitate this decision. Two values are needed: - P-SEAMLDR version: for compatibility checks between TDX module and P-SEAMLDR - num_remaining_updates: indicates how many updates can be performed Expose them as tdx-host device attributes visible only when updates are supported. Note that the underlying P-SEAMLDR attributes are available regardless of update support; this only restricts their visibility to userspace.
