Allow disabling non-FIT image loading from SPL

Hello all,

To address a needed feature brought up by Andreas[0], we need a way to disable SPL from loading non-FIT images.

The function spl_parse_image_header is common to all SPL loading paths (common/spl/spl_(nand|net|nor|etc..)) so we add the check here.

This version of the series is a bit different than the first few due to suggestions by Simon, instead of a negative option disabling non-FIT images, we allow the other image format's support to be toggled off, and do that on HS boards.

Thanks,
Andrew
