Hello,

This series fixes two issues related to the pcie3x4 slot on the rk3588:
1) Adds the atu region, so that the driver can properly detect all 16
inbound iATUs and all 16 outbound iATUs.
2) Adds the dma region, and the related IRQs used by the eDMA, so that it
is possible to offload data transfers using the embedded DMA controller.


Changes since v1:
-Added patches to rockchip-dw-pcie.yaml to make 'make CHECK_DTBS=y' pass.


Kind regards,
Niklas
