[U-Boot] [PATCH 1/9] dm: pci: return the real controller in pci_bus_to_hose()

[M.H. Lian]

Hi Bin，

Thanks for your comments.

The series of patches is to change legacy PCIe driver to DM PCIe driver.
The first two patches are to change DM to support multiple PCIe controllers.
The 8th patch is to change Layerscape PCIe driver based on DM
Other patches are to add PCIe dts node for five SoCs.

Thanks,
Minghuan
