[PATCH] ARM64: dts: Layerscape: workaround v6.19-rc1 DT sync DWC3 breakage

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Upstream Linux commit 7b204755ebc2 ("arm64: dts: layerscape: add
dma-coherent for usb node") has dropped the snps,dwc3 compatible in
favor of a driver matching against fsl,ls1028a-dwc3.

Reinstate the old compatible temporarily to avoid breakage in the
next release until the new driver is added regularly.

The new driver was deemed too invasive for master as it also does some
hardware configuration we will want to carry and involved some changes
to DWC3 core.

Fixes: a3bf6c16f77d ("dts: update to v6.19-rc1")
