Make two calls into one by using devm_platform_ioremap_resource().

Please don't do this. See the previous commit:
4ed7d7dd4890bb8120a3e77c16191a695fdfcc5a ("Revert "gpio: eic-sprd: Use
devm_platform_ioremap_resource()"")


Ah, I see. Dropped. Could use a comment describing the problem though.

Yes, I think so, in case someone does the same thing in the future.
