iommu/rockchip: Add missing set_platform_dma_ops callback
Similar to exynos, we need a set_platform_dma_ops() callback for proper
operation on ARM 32 bit after recent changes in the IOMMU framework
(detach ops removal). But also the use of a NULL domain is confusing.
Rework the code to add support for IOMMU_DOMAIN_IDENTITY and a singleton
rk_identity_domain which is assigned to domain when using an identity
mapping rather than "detaching". This makes the code easier to reason about.
