iommu/tegra: Fix incorrect size calculation
This driver uses a mixture of ways to get the size of a PTE,
tegra_smmu_set_pde() did it as sizeof(*pd) which became wrong when pd
switched to a struct tegra_pd.
Switch pd back to a u32* in tegra_smmu_set_pde() so the sizeof(*pd)
returns 4.
Fixes: 50568f87d1e2 ("iommu/terga: Do not use struct page as the handle for as->pd memory")
