Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.
