Add Rockchip u-boot "binman" BOOT_SCENARIO (#7505)

* rockchip64: add `BOOT_SCENARIO=binman` for mainline u-boot - drop special handling for 3308's `legacy` branch - rpardini: note how SPI/mtd is not yet supported for this scenario Co-authored-by: Ricardo Pardini <[email protected]> (squash/splits, shellfmt) * `rock-s0`/`rockpi-s`: use `BOOT_SCENARIO=binman`; move blobs to armbian/rkbin - Move rk3308 boot blobs to armbian/rkbin - delete obsolete ones - Alter rock-s0 and rockpi-s to use the new "binman" BOOT_SCENARIO Co-authored-by: Ricardo Pardini <[email protected]> (shellfmt; small fixes; squashes)
