H A Dmtk_iommu.cdiff 6b717796227ec8d4303adcdc574165d06e499f0f Fri Jul 03 06:41:20 CEST 2020 Chao Hao <chao.hao@mediatek.com> iommu/mediatek: Use a u32 flags to describe different HW features

Given the fact that we are adding more and more plat_data bool values,
it would make sense to use a u32 flags register and add the appropriate
macro definitions to set and check for a flag present.
No functional change.
