Ugh, I've completely forgotten that this file has a part dedicated to
starting up the swtpm program!

The text file itself is referenced near the top of
"OvmfPkg/Include/IndustryStandard/QemuTpm.h". Now that I looked again at
the text file, I only expected to see the device interface, and was
surprised by the "swtpm" instructions :)

Very nice.

Thanks!
