d6c10360dc pci: pcie_dw_meson: fix usb fail when pci link fails to go up 
On Amlogic A311D, when the PCIe link fails disabling the related clocks
makes USB fail. For an unknown reason, this doesn happen on the S905D3 SoC.

Mimic the Linux behavior by not considering a link failure a probe failure,
and continue even if the PCIe link is down.

Add support for the DW PCIe controller found in the Amlogic Meson AXG and
G12 (G12A, G12B, SM1) SoCs.
This uses the common DW PCIe helpers introducted previously.
