msm: kgsl: Enable the iommu halt feature for certain IOMMU versions 



Enable the IOMMU halt feature for non v0 IOMMU versions instead of
depending on the feature being enabled in the IOMMU device tree.
This is because on certain chipsets this feature is not set in
the device tree even if the IOMMU h/w supports it.
