iommu/arm: Remove arch_iommu_populate_page_table() completely

The Arm realization should have been removed in the following commit
as redundant:
f89f555 remove late (on-demand) construction of IOMMU page tables

So, remove unused function completely.

Fixes: f89f555 ('remove late (on-demand) construction of IOMMU page tables')
