Change the SPL boot selection of MMC from a hard selection of GPIO to a softer imply and opt-out of GPIO support for helios4. This preserves the previous GPIO-less configuration.

Aditya Prayoga - if you object to the addition of GPIO to the helios4 SPL, I'd be interested in your thoughts on this option
This is an exploratory commit of a viable approach to retain the identical current helios4 current configuration. I think it's not worth it and shouldn't be applied since helios4 uses default MMC boot and there is sufficient space for the SPL image, but is a viable option depending on the opinion of helios4 interested maintainers.
