iommu/omap: Remove omap_iommu_arch_version() and version field

Browse Source 
The function omap_iommu_arch_version() is not used anymore,
and is not required either, so remove it. The .version field
in struct iommu_functions that this function uses is also
removed, as it is not really an ops to retrieve a version and
there won't be any usage for this field either.
