virtio-serial: use aliases instead of duplicate qdev properties
virtio-serial-{pci, s390, ccw} all duplicate the
qdev properties of their VirtIOSerial child.
This approach does not work well with string or pointer
properties since we must be careful about leaking or
double-freeing them.
Use the QOM alias property to forward property accesses to the
VirtIOSerial child. This way no duplication is necessary.
