x86: Unify arch/io.h and arch/romcc_io.h

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.
