Subject: [PATCH] arm64: dts: qcom: sc7280-herobrine: Don't enable the USB 2.0 port

The USB 2.0 port of sc7280 is currently not used by any herobrine
board. Delete the device tree entries that enable it.

Signed-off-by: Matthias Kaehlcke <mka@...omium.org>

I was also told that the 2.0 port is for the Embedded USB Debugger
(EUD) only, but I'm not sure if that's true. From the Linux side
it looks like a regular dwc3 controller.
