[IA64] enable setting DMAR on by default
The previous commit which introduced the DMAR_DEFAULT_ON setting in drivers/pci/dmar.c neglected to add the ability for ia64 to enable the IOMMU by default. Rectify that mistake, doh! Signed-off-by: Kyle McMartin <kyle@redhat.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
