This series fixes some issues in rockchip iommu driver, and add of_iommu
support in it.

Changes in v5:
Use out labels to save the duplication between the error and success paths.
Use RK_MMU_POLL_PERIOD_US instead of 100.
Remove clk names.
Use clk_bulk APIs.
Avoid race about pm_runtime_get_if_in_use() and pm_runtime_enabled().

Changes in v4:
Rewrite commit message.

Changes in v3:
Also remove remove() and module_exit() as Tomasz suggested.
Loop platform_get_irq() as Robin suggested.
Add struct rk_iommudata.
Squash iommu/rockchip: Use iommu_group_get_for_dev() for add_device
Only call startup() and shutdown() when iommu attached.
Remove pm_mutex.
Check runtime PM disabled.
Check pm_runtime in rk_iommu_irq().
Remove rk_iommudata->domain.

Changes in v2:
Move irq request to probe(in patch[0])
Move bus_set_iommu() to rk_iommu_probe().
