arm64: dts: imx8mm-var-som-symphony: Move USB configuration from SOM

Browse source

Move the USB controller configuration out of the i.MX8MM VAR-SOM dtsi
and into the VAR-SOM Symphony carrier board dts.

The SOM does not provide any USB connectors and carrier boards may
choose whether and how to route USB, therefore USB should be described
in the carrier-specific device tree instead of the SOM include.

While moving the nodes, align the Symphony USB description with the
carrier design by enabling both USB controllers, wiring USB1 to the
PTN5150 Type-C controller for dual-role operation, and updating the
PHY tuning and VBUS regulator pinctrl (including a sleep state).
