With the introduction of pcie_dw_rockchip, and need to support the DW PCIe in

Amlogic AXG & G12 SoCs, most of the DW PCIe helpers would be duplicated.
This introduce a "common" DW PCIe helpers file with common code merged from the
dw_ti and dw_rockchip drivers and adapted to fit with the upcoming dw_meson.
That's a good idea.
BTW, pcie_dw_mvebu.c and pcie_imx.c also should need a migration.
The following changes will switch the dw_ti and dw_rockchip, and introduce a new
driver to support the Amlogic AXG & G12 SoCs using these new common helpers.
The dw_meson has been validated, but the dw_ti and dw_rockchip would need
testing
on hardware to validate nothing has been broken.
