tools: imximage: Load a size that is multiple of 512
In order to mx53 ROM to properly load the U-boot image, its header size should
be multiple of 512 bytes.
This issue was observed with gcc 4.6.2/4.7.3, which caused data aborts:

,and this patch fixes it.
Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."
