iommu/mediatek: Add iova reserved function
For multiple iommu_domains, we need to reserve some iova regions. Take a example, If the default iova region is 0 ~ 4G, but the 0x4000_0000 ~ 0x43ff_ffff is only for the special CCU0 domain. Thus we should exclude this region for the default iova region. Signed-off-by:Anan sun <anan.sun@mediatek.com> Signed-off-by:
