powerpc/boot: Allocate more memory for dtb
David Gibson suggested that since we are now unconditionally copying the dtb into a malloc()ed buffer, it would be sensible to add a little padding to the buffer at that point, so that further device tree manipulations won't need to reallocate it. This implements that suggestion. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
