usb: typec: intel_pmc_mux: Defer probe if SCU IPC isn't present
[ Upstream commit df9a825f330e76c72d1985bc9bdc4b8981e3d15f ]
If pmc_usb_probe is called before SCU IPC is registered, pmc_usb_probe
will fail.
Return -EPROBE_DEFER when pmc_usb_probe doesn't get SCU IPC device, so
the probe function can be called again after SCU IPC is initialized.
