The Genio 510 and Genio 700 boot chains use a platform DDR loader built
separately from U-Boot to initialize DRAM before entering U-Boot SPL. Add
the shared SPL devicetree and configuration needed to initialize the debug
UART, watchdog, pinctrl and eMMC, then load a conventional FIT from the
bootloaders GPT partition.
Add an opt-in binman description that generates the images consumed by
the MediaTek flashing flow:
mtk-boot.bin
MediaTek BootROM wrapper containing the platform DDR loader and SPL
mtk-boot-payload.bin
Raw DDR-loader and SPL payload for external MediaTek signing tools
bootloaders.img
FIT containing BL31, OP-TEE, U-Boot proper, and its control DT

Changes in v3:
- Add Genio 510 support using the shared MT8188-family SPL configuration,
pre-RAM devicetree annotations and binman layout.
- Make complete image packaging opt-in through CONFIG_MTK_BOOT_IMAGES.
- Keep the binman image description in a separate optional include.
- Leave SPL binman symbols disabled by default on MT8188.
- Add optional RSA-3072 signing for the bootloader FIT.
- Emit the raw BootROM payload required by external MediaTek signing tools.
- Document component-only, unsigned, and signed build procedures.

Changes in v2:
- Clarify that the platform DDR loader is built separately from U-Boot.
- Fix the SPL copy-window wording in patch 2.
- Keep the SPL annotations board-scoped and drop the unused pericfg_ao tag.
- Normalize the firmware-stage names in the board documentation.
- Simplify the documented build commands.
- Remove the redundant MediaTek documentation maintainer pattern.
- Add links to Genio Tools and prebuilt images.
