iommu/arm-smmu: fix incorrect use of S2CR_TYPE_SHIFThisi-smmu-v1.1.1
There is already S2CR_TYPE_SHIFT in S2CR_TYPE_TRANS macro, so drop the second shift. Note that, since S2CR_TYPE_SHIFT is 0x0, there is no functional change introduced by this patch. Signed-off-by: Kefeng Wang <wangkefeng.wang@huawei.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
