Select AMD SOCs include the ability to export capabilities that
have been activated or detected by the platform security processor.

This information is useful for both system designers as well as system
administrators to ensure that the system has been properly locked down
to their expectations.

Software such as fwupd will also be modified to use this information
as part of the calculations for a security level score that may be
presented to a user.

This series also adds the ability to detect that TSME and SME are both
activated simultaneously to notify a user.  Previously a user could turn
on TSME and SME at the same time, but the kernel was unable to detect
that TSME was enabled in the OS.

This information is evaluated "too late" right now in the kernel to stop
the kernel from enabling SME, but if that is desirable at a later time
some of the early code can be modified to read the same information and
make that decision.
