iommu/qcom: Fix pgsize_bitmap
qcom uses the ARM_32_LPAE_S1 format which uses the ARM long descriptor
page table. Eventually arm_32_lpae_alloc_pgtable_s1() will adjust
the pgsize_bitmap with:
cfg->pgsize_bitmap &= (SZ_4K | SZ_2M | SZ_1G);
So the current declaration is nonsensical. Fix it to be just SZ_4K which
is what it has actually been using so far. Most likely the qcom driver
copy and pasted the pgsize_bitmap from something using the ARM_V7S format.
Fixes: db64591de4b2 ("iommu/qcom: Remove iommu_ops pgsize_bitmap")
