Hi,

Some rockchip iommus require extra clocks besides aclk and interface
clock, such as the iommus for NPU and RKVENC in RK3576.

Changes in v2:
- Link to v1: https://lore.kernel.org/all/20251126083345.88-1-kernel@airkyi.com/
- Rewrite dt binding.

  dt-bindings: iommu: rockchip: Add support for multiple interface
    clocks
  iommu/rockchip: Use devm_clk_bulk_get_all() to get multiple iface
    clock
