linux, efi, arm*, fdt: Break FDT extra allocation space out into a #define

Browse source 
A certain amount of dynamic space is required for the handover from
GRUB/Linux-EFI-stub. This entails things like initrd addresses,
address-cells entries and associated strings.

But move this into a proper centralised #define rather than live-code
it in the loader.
