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.
