Extend the TPM backend XML with a node 'active_pcr_banks' that allows a
user to specify the PCR banks to activate before starting a VM. Valid
choices for PCR banks are sha1, sha256, sha384 and sha512. When the XML
node is provided, the set of active PCR banks is 'enforced' by running
swtpm_setup before every start of the VM. The activation requires that
swtpm_setup v0.7 or later is installed and may not have any effect
otherwise.
