hw/qdev-clock: Avoid calling qdev_connect_clock_in after DeviceRealize
Clock canonical name is set in device_set_realized (see the block
added to hw/core/qdev.c in commit 0e6934f264).
If we connect a clock after the device is realized, this code is
not executed. This is currently not a problem as this name is only
used for trace events, however this disrupt tracing.
Add a comment to document qdev_connect_clock_in() must be called
before the device is realized, and assert this condition.
