media: rockchip: rga: support external iommus

Browse source

In preparation for the RGA3 add support for external iommus. This is a
transition step to just disable the RGA2 specific mmu table setup code.

Currently a simple rga_hw struct field is used to set the internal iommu.
But to handle the case of more sophisticated detection mechanisms
(e.g. check for an iommu property in the device tree), it is abstracted
by an inline function.
