No you don't.

The I/O space window will only be in one place on a given system, so you
should register that window using pci_ioremap_io() as all the other
modern platforms. There is no excuse for having a per-platform mach/io.h
any more and that would prevent you from enabling spear in a multiplatform
configuration.
