[PATCH] arm64: dts: mediatek: tungsten-smarc: Remove unnecessary cells

[AngeloGioacchino Del Regno]

Remove unnecessary address and size cells from both the disp_dsi0
and the xhci2's ethernet usb device subnode to fix a dtbs_check
warning for avoid_unnecessary_addr_size.

Fixes: 9fda4a8a479f ("arm64: dts: mediatek: add device tree for Tungsten 510 board")

Out of curiosity, how did you get those warnings? I ran my check dtbs
command on v7.2-rc3 and couldn't see anything related:
$ make CHECK_DTBS=y mediatek/mt8370-tungsten-smarc.dtb
