[PATCH] iommu: dmar: make include of x86_init.h conditional

[Arnd Bergmann]

The dmar driver can be used on both x86 and itanium, but only
the former uses the x86_init structure. The only reference to
that structure is enclosed in an #ifdef, but the header inclusion
I added is not.

Adds another #ifdef to get ia64 to build again.

Fixes: 0f5a0f4f062c ("x86: don't include asm/x86_init.h in asm/setup.h")
