pci: pcie_dw_common: introduce pcie_dw_find_capability()
Add PCIe config space capability search function specific for
the host controller, which are bridges *to* PCI devices but
are not PCI devices themselves.

d678a59d2d Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

4c56d75117 drivers: pci: pcie_dw_common: add upper-limit to iATU
The 4.6 spec added an upper 32bits to the ATU limit, and since this
driver is already assuming the unrolled feature added in the 4.8
specification this really should be set.

This is causing a bug with testing against the QEMU model as it
defaults the viewports to fully open and not setting this causes
the config viewport to become most of memory (obviously stopping
the emulated system working correctly)

dfadb946f6 pci: add common Designware PCIe functions
With the introduction of pcie_dw_rockchip, and need to support the DW PCIe in the
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.

The following changes will switch the dw_ti and dw_rockchip to use these helpers.
