As we discussed in the past, the EFI TCG code can't be tested with the
asndbox as-is.  I'll have a look on your sandbox patches in case we can now
use those, but in any case, I've sent a TPM mmio based driver.  Even if the
sandbox is still not enough we can add tests once the mmio TPM driver gets
merged
