Subject: [PATCH] arm64: dts: imx8mq: disable SuperSpeed instances in park mode
This seem to have solved the issue of the modem disappearing completely
during a usb reset (though doesn't seem to do anything for the resets
themselves).
This change was suggested by Martin Kepplinger in
https://source.puri.sm/Librem5/linux-next/-/issues/197#note_114221
