This has no effect. You are assigning the same variable 3 times. It 
needs to be every overlay applied to its base is a *-dtbs variable and 
then those are all added to 'dtb-y'. IOW, we don't allow overlays which 
can't be applied at build time.

Assuming the overlays aren't mutually exclusive, you could do:

mtk-mt8365-pumpkin-dtbs := mt8365-pumpkin.dtb mt8365-pumpkin-ethernet-usb.dtbo
mtk-mt8365-pumpkin-dtbs += mt8365-pumpkin-csi0-thp7312-imx258.dtbo
mtk-mt8365-pumpkin-dtbs += mt8365-pumpkin-csi1-thp7312-imx258.dtbo

This works the same way as '-objs' variables to group .o files into a 
module.

Looks like mtk-mt8365-pumpkin.dtb failed to get built before. In any 
case, that's a terrible name. What's the difference between 
mt8365-pumpkin.dtb and mtk-mt8365-pumpkin.dtb? There's no clue.
