[PATCH v2 1/2] iommu/arm-smmu-v3: Avoid open coded arithmetic in memory allocation

kmalloc_array()/kcalloc() should be used to avoid potential overflow when a multiplication is needed to compute the size of the requested memory. So turn a devm_kzalloc()+explicit size computation into an equivalent devm_kcalloc(). Signed-off-by: Christophe JAILLET Acked-by: Robin Murphy ---
