Subject: fix 'Merge 32 and 64 bits asm-powerpc/io.h'

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Fixes a typo causing various problems mostly with PCI IO space. Change
from previous version is in io.h, near the top,

 #ifdef CONFIG_PCI -> #ifndef CONFIG_PCI

Thanks to Guennadi Liakhovetski for spotting it.
