powerpc/boot: Compare _start against ei.loadsize instead ei.memsize
If the vmlinux binary in memory is larger than 4 MiB than it collides with the initial boot code which is linked at 4 MiB in case of cuBoot. If the the uncompressed image size (on disk size) is less than 4 MiB then it would fit. The difference between those two sizes is the bss section. In cuBoot we have the dtb embedded right after the data section so it is very likely that the reset of the bss section (in kernel's start up code) will overwrite the dtb blob. Therefore we reallocate the dtb. Something similar is allready done to the initrd.
