[PATCH v3 5/6] arm: dts: mediatek: emit the Genio 510 and 700 BootROM payload

MediaTek secure-boot tooling signs the raw DDR-loader and SPL payload
before adding the BootROM headers. Signing mtk-boot.bin would instead
sign an image that already carries the unsigned headers.

Have binman emit the existing payload section as mtk-boot-payload.bin.
This keeps the fixed DDR-loader and SPL layout in one description and
does not change mtk-boot.bin.
