Introduce another SIZE_CHECK macro for u-boot-with-spl.bin.
Note that we cannot reuse BOARD_SIZE_LIMIT here, as this also applies to
intermediate u-boot*bin images, which, before being compressed, may be
larger than the final combined image.
Also SPL_SIZE_LIMIT has to be a separate option, as some boards might
just want to restrict SPL size while still allowing u-boot-with-spl.bin
to be bigger.
