All the other SPL loaders are in this directory, so move the SPI one in there too.

There are two board-specific SPI loaders (fsl and sunxi). These remain in the drivers/mtd/spi directory, since they do not contain generic code.

Rather than having a global variable, pass the spl_image as a parameter. This avoids BSS use, and makes it clearer what the function is actually doing.

There is no need for this to be in the BSS region. By moving it we can delay use of BSS in SPL. This is useful for machines where the BSS region is not in writeable space. On 64-bit x86, SPL runs from SPI flash and it is easier to eliminate BSS use than link SPL to run with BSS at a particular cache-as-RAM (CAR) address.
