Subject: [PATCH 1/4] arm64: dts: qcom: x1e001de-devkit: Fix swapped USB MP
 repeaters

The &eusb3_repeater belongs to the first port of the USB MP controller and
the &eusb6_repeater belongs to the second. This is obvious if one looks at
e.g. the CRD or the Dell XPS where only the second port of the USB MP is
used: They only have the &eusb6_repeater and already specify it for the
&usb_mp_hsphy1.

Swap them to set the correct repeater for each of the USB ports.

Fixes: d12fbd11c5a3 ("arm64: dts: qcom: x1e001de-devkit: Enable support for both Type-A USB ports")
