rockchip64: fix OrangePi 4 LTS boot with BTF, bump uboot to 2024.10

[paolosabatino]

Description

At last I found, after quite a lot of headaches, that the OrangePi4 LTS booting issues with BTF-enabled kernels was not due to old u-boot, relocation issues or overlapping segments. Instead it was the utterly crappy (but woking) DMC driver that, when BTF is enabled, becomes an utterly crappy non working driver.

I disabled it and - magically - everything is fixed now.

In the meantime, believing the issue was in u-boot, I bumped u-boot to v2024.10 with little to almost no pain.
Some considerations:

• binman does a great job
• BOOT_SCENARIO=binman is already available for rockchip64 targets, idbloader and u-boot.itb are built by u-boot/binman, without doing it "manually" in the armbian family include script
• important is to use CONFIG_ROCKCHIP_EXTERNAL_TPL=y in u-boot config if the board wants the proprietary ddrbin, otherwise u-boot will use its own TPL as ddr initialization binary
