scripts: sunxi: Build an raw SPL image

Browse Source 
Introduce a new sunxi-spl-with-ecc.bin image with already the right header,
ECC, randomizer and padding for the BROM to be able to read it.

It needs to be flashed using a raw access to the NAND so that the
controller doesn't change a thing to it, since we already have all the
right parameters.
