[PATCH v2] arm64: dts: imx95-navq: add USB1/USB2 nodes

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

Add and enable the DT nodes for USB1 and USB2.

Signed-off-by: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>
---
v1 -> v2:

* change USB2 DR mode to OTG to match TypeC connector configuration. The
controller should actually support the software-based host <-> device
switch.
