Add support for setting linux,usable-memory property in the memory node of device tree for the kernel [1].

Isn't this same/similar to fdt_add_mem_rsv() ?

I would say they are opposite :) - linux,usable-memory property let the kernel be aware about all the memory he can use. - memreserve - what memory to exclude.

I think both should be helpful.
