Not other architectures does this, and we plan to get rid of ioremap_nocache. So get rid of the special semantics and define ioremap_nocache in terms of ioremap as no portable driver could rely on the behavior anyway. However x86 implements ioremap_uc with a in a similar way as the ia64 version of ioremap_nocache, so implement that instead.
