Describe x2 Parade PS8830 retimers for left and right USB Type-C ports respectively. Adjust graphs between connectors and the PHYs accordingly, add the voltage regulators. Dell XPS 13" 9345's DSDT describes 3rd retimer, but its not actually present. Regulators are _assumed_ to be correct, since: * tlmm pins match DSDT definition. * tlmm and pmic gpios were tested and confirmed to be powering off/resetting respective retimers. * USB3.0 now works correctly in both orientation, pre and post suspend.
