image: Add CONFIG_FIT_SPL_PRINT to control FIT image printing in SPL

This code is very large, and in SPL it isn't always useful to print
out image information (in fact there might not even be a console
active). So disable this feature unless this option is set.

+		Printing information about a FIT image adds quite a bit of
+		code to SPL. So this is normally disabled in SPL. Use this
+		option to re-enable it. This will affect the output of the
+		bootm command when booting a FIT image.
