On systems with large amount of memory, loading kdump kernel through kexec_file_load syscall may fail with the below error:

"Failed to update fdt with linux,drconf-usable-memory property"

This happens because the size estimation for kdump kernel's FDT does not account for the additional space needed to setup usable memory properties. Fix it by accounting for the space needed to include linux,usable-memory & linux,drconf-usable-memory properties while estimating kdump kernel's FDT size.

Applied to powerpc/next.
