Platforms which use raw zboot images may need to link the image at a fixed address if there is no other way to communicate the load address to the bootloader. Allow the per-platform Kbuild files to specify an optional zboot image load address (zload-y) and fall back to calc_vmlinuz_load_addr if unset.
