We already have "linux,usable-memory" on /memory node:
https://elixir.bootlin.com/linux/v5.13-rc6/source/drivers/of/fdt.c#L1011
and it makes perfect sense to be there since it overrides /memory's reg 
property.

Why define another binding for the same thing on /chosen ?

I'll add the entry from kexec-tools, so that the kernel will reserve the 
region as part of:
