This patch extends the TPM's device XML with TPM 2 support. This

for the emulator type backend and looks as follows:

<backend type='emulator' version='2'/>

The swtpm process now has --tpm2 as an additional parameter:
system_u:system_r:svirt_t:s0:c597,c632 tss 18477 11.8 0.0 28364 3868 ? Rs

dir=/var/lib/libvirt/swtpm/testvm/tpm2,mode=0640 --log
file=/var/log/swtpm/libvirt/qemu/testvm-swtpm.log --tpm2 --pid
file=/var/run/libvirt/qemu/swtpm/testvm-swtpm.pid
The version of the TPM can be changed and the state of the TPM is preserved.

Too bad we're stuck with help scraping for swtpm_setup rather than using
some sort of ioctl to get the version support...
