Build the (upstream) configuration for the MT7987 reference board, and enable support for DT-overlay application which will be necessary to use the image for the MT7987 RFB generated in OpenWrt. Adapt our downstream patches (generic reset button, rootdisk selection) for MT7987 to prepare for real-world boards. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
