usb: typec: tcpm: remove tcpm dir if no children
If config tcpm as module, module unload will not remove tcpm dir,
then the next module load will have problem: the rootdir is NULL
but tcpm dir is still there, so tcpm_debugfs_init() will create
tcpm dir again with failure, fix it by remove the tcpm dir if no
children.
