spl: Convert CONFIG_SPL_ABORT_ON_RAW_IMAGE into a positive option

CONFIG_SPL_ABORT_ON_RAW_IMAGE causes SPL to abort and move on when it
encounters RAW images, express this same functionality as a positive
option enabling support for RAW images: CONFIG_SPL_RAW_IMAGE_SUPPORT

Also move uses of this to defconfigs.
