[PATCH v2 07/22] usb: typec: tipd: Move switch_power_state to tipd_data

[Sven Peter <sven@kernel.org>]

When support for CD321x was originally added no other hardware variant
was supported and there was no need for struct tipd_data. Now that it
exists move the special case in there so that we can drop the
of_device_is_compatible_check entirely.
