volteer: dts: define and instantiate the retimer device on the i2c mix bus
Define a device tree binding for the JHL8040R retimer and instantiate it
on the i2c3_0 (USB_1_MIX) bus.
Adding a label so that it can be retrieved directly with a DT_NODELABEL
directly until the driver is ported to enumerate based on the compatible
property.
BUG=b:176505554
TEST=build and checked zephyr.dts manually
