[libvirt] [PATCH 01/12] Revert "qemu: Support chardevs with ARM virt machines"

This reverts commit 70c9b44270f75bfb7a5701d81aa49380d139e8f0.

This commit breaks existing aarch64 machvirt configs with:

    <serial type='pty'>
      <target port='0'/>
    <console type='pty'>
      <target type='serial' port='0'/>

Which fails with:

error: Failed to start domain fedora25-aarch64
error: internal error: process exited while connecting to monitor:
2017-06-26T13:55:34.726293Z qemu-system-aarch64: -chardev pty,id=charserial0:
