Removes the machine parameter to proc_iomem() which is no
longer of any use.

When I first added proc_iomem() it was for ia64 Xen as
certain regions are added /proc/iomem_machine instead of /proc/iomem
on that platform.
On further examination I have found that all regions need to be
added to /proc/iomem_machine.
This patch changes the ia64 implementation of proc_iomem()
to always return /proc/iomem_machine if xen is in use.
A subsequent patch will remove the machine parameter to proc_iomem() which
is no longer of any use.

Use /proc/iomem_machine for ia64 xen where pysical and machine efi maps
differ. Without this kexec gets a very jaded view of the world, and
/proc/vmcore after a kdump will only have a partial memory dump. Requires a
companion patch to kexec-tools.
