This is too big to ask for right now, 100% of the RK3588 products in 
upstream U-Boot have CONFIG_SPL_ATF_NO_PLATFORM_PARAM set.

Does it hurt to keep it forever?

And what if we have OP-TEE without this node present, which would be 
possible if we have CONFIG_SPL_ATF_NO_PLATFORM_PARAM set in U-Boot?

I guess we could detect from U-Boot if a TEE is loaded as part of 
u-boot.itb and fixup the DTB otherwise to mark this node as status = 
"disabled"?
