[PATCH 24/24] qemu: command: Use 'qemuBuildChrChardevCommand' to build TPM backend

Thu Dec 9 12:30:59 UTC 2021
Since the backend of the TPM is a chardev we can use the common helper
to instantiate it.
This commit also ensures proper ordering so that the backend chardev is
formatted before it's being referenced.
