[Fedora-xen] [RFC] cleanup warning (redefine MMIO_SIZE)

[Akio Takebe]

Hi, all

This issue is only for fedora-xen-ia64.
fedora-xen-ia64 turn on CONFIG_FB_NEOMAGIC in .config.
(xen-ia64-unstable is default turn off it)
In the case of CONFIG_FB_NEOMAGIC=y, MMIO_SIZE is redefine.
I think MMIO_SIZE in arch-ia64.h is only used 
in arch-ia64.h and xen/arch/ia64/vmx/vmx_init.c.
Am I right?

We should move some defines(e.g. MMIO_xxx) from public header
to not public header because they are used only 
in vmx_init.c, shouldn't we?

fedora-xen-ia64's warning is:
