The DPU driver isn't expected to be used without an IOMMU. Thus the aspace will be always present. Not to mention that mdp4/mdp5 drivers call msm_framebuffer_iova() without such checks, as the whole msm_framebuffer layer is expected to support both IOMMU and IOMMU-less configurations. Drop these useless if (aspace) checks.
