[PATCH] ARM: Orion5x - Restore parts of io.h

[Andrew Lunn]

Commit 4d5fc58dbe34b78157c05b319669bb3e064ba8bd remove the orion5x
io.h. Unfortunetely, this is still needed for the definition of
IO_SPACE_LIMIT which overrides the default 64K. All Orion based
systems have 1Mbyte of IO space per PCI[e] bus, and try to
request_resource() this size.
