Move iop13xx PCI to fixed i/o mapping and remove io.h.
This changes the PCIe bus address to start at 0x10000. Let's hope this
works. If it does not, the alternative would be to revert the value we
write into OIOTVR to zero and set sys->io_offset to 64K.

iop13xx confuses I/O port numbers with physical addresses, which breaks
legacy ISA I/O access behind PCI bridges and makes it unnecessarily hard
to unify the inb/outb accessors with other platforms. This removes the
special-casing and just puts all I/O ports into a single 128KB virtually
mapped I/O port range starting at port zero.

__mem_pci is only used to enable readl/writel and friends. Just condition
this on readl being defined and remove all the __mem_pci defines.

These variables are just needed in pci.c and io.c, so move them out of
io.h in preparation to remove io.h.

Convert iop13xx platforms to use run-time ioremap hook instead of the
compile time hook. The custom ioremap is still needed for 64-bit address
handling.

Defining iounmap() with arguments prevents it from being used as a
function pointer, causing platforms to work around this. Instead,
define it to be a simple macro.
Do the same for __arch_io(re|un)map too.

This just leaves include/asm-arm/plat-* to deal with.
