Fix USB-related warnings in prtrvt, prtvt7, prti6q and prtwd2 device trees
by disabling unused usbphynop1 and usbphynop2 USB PHYs and providing proper
configuration for the over-current detection. This fixes the following
warnings with the current kernel:
 usb_phy_generic usbphynop1: dummy supplies not allowed for exclusive requests
 usb_phy_generic usbphynop2: dummy supplies not allowed for exclusive requests
 imx_usb 2184200.usb: No over current polarity defined

By the way, fix over-current detection on usbotg port for prtvt7, prti6q
and prtwd2 boards. Only prtrvt do not have OC on USB OTG port.

The imx6qp-prtwd3 board supports USB over current detection on the USB
OTG port, however, it was previously disabled in the device tree. This
commit enables the over current detection by changing the device tree
setting from 'disable-over-current' to 'over-current-active-low'. This
could potentially protect the USB port from damage due to over current
situations.

This patch addresses several USB-related warnings in the device tree for
the imx6dl vicut1 system. Specifically, it disables the unused
usbphynop1 and usbphynop2 USB PHYs, and disables unsupported
over-current detection. This action mitigates the following kernel
warnings:
usb_phy_generic usbphynop1: dummy supplies not allowed for exclusive requests
usb_phy_generic usbphynop2: dummy supplies not allowed for exclusive requests

Kernel v6.3-rc1 prints errors due to missing trip points in thermal
zones. These errors indicate a lack of critical temperature threshold
settings, causing warnings at boot. To silence these errors, this patch
introduces trip points into the thermal zones of several imx6dl based
devices.

The following devices are updated:
- plym2m
- prtvt7
- victgo
- vicut1

These devices are automotive grade and expected to operate up to 105C.
An exception is the plym2m, an industrial grade device, which is
certified to work up to 85C.

The added trip points act as alert thresholds but do not trigger any
actions except warnings. This behavior is by design, as these devices
should maintain their performance until the end, without any thermal
throttling.

This commit adds the 'over-current-active-low' flag to the USB OTG node
in the imx6dl-lanmcu device tree. This flag is necessary because the
hardware signals over-current conditions by pulling the line low.
Without this flag, the kernel could misinterpret an over-current
condition, leading to unexpected behavior.

In the imx6dl-lanmcu system, the usbh2 and usbh3 interfaces are not in
use. However, the related USB PHY nodes (usbphynop1 and usbphynop2) are
enabled by default in the imx6qdl.dtsi file, which can lead to confusion
and potential resource mismanagement.

This commit explicitly disables these unused USB PHY nodes in the
imx6dl-lanmcu device tree, aligning the configuration more accurately
with the actual hardware setup.
