So far the puma dts files only just included the main puma dtsi without handling the actual baseboard and rk3399-puma.dtsi was very much detached from the variant in the mainline Linux kernel. Recent changes resulted in a strange situation with nonworking puma boards. Commitab800e5a6f("arm: dts: rockchip: puma: move U-Boot specific bits to u-boot.dtsi") moved the sdram include from rk3399-puma-ddrX.dts to new files rk3399-puma-ddrx-u-boot.dtsi which were never included anywhere though. Commit167efc2c7a("arm64: dts: rk3399: Sync v5.7-rc1 from Linux") replaced the rk3399-puma.dtsi nearly completely, but in the kernel it definitly depends on a baseboard dts to actually enable peripherals like sd-slot, uarts, etc. So to untagle this and bring the whole thing more in line with mainline Linux, bring the rk3399-puma-haikou.dts over as well, drop the separate DDR-option devicetrees and instead replace them with a puma Kconfig option to select and include the needed DDR variant.
