Due to a long-standing issue in driver core, drivers may not probe defer after having registered child devices to avoid triggering a probe deferral loop (see fbc35b45f9f6 ("Add documentation on meaning of -EPROBE_DEFER")). Move registration of the typec switch to after looking up clocks and other resources. Note that PHY creation can in theory also trigger a probe deferral when a 'phy' supply is used. This does not seem to affect the QMP PHY driver but the PHY subsystem should be reworked to address this (i.e. by separating initialisation and registration of the PHY).
