fdt_resize(): ensure minimum padding
fdt_add_mem_rsv() requires space for a struct fdt_reserve_entry (16 bytes), so make sure that fdt_resize at least adds that much padding, no matter what the location or size of the fdt is. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Acked-by: Andy Fleming <afleming@freescale.com>
