The Symphony carrier board includes a USB Type-C connector on the USB1
port through an NXP PTN5150 Type-C controller connected on the I2C bus.
The PTN5150 provides cable orientation detection and role switching
information to the USB controller.
This patch adds the PTN5150 node, its interrupt line, the required pin
muxing, and wires the controller to the USB1 OTG dual-role device using
the USB role-switch framework.
This patch adds also USB2 support, that remains in host-only mode,
matching the hardware capabilities of the Symphony board.
