MediaTek's PCIe host controller has two generation HWs, the new
generation HW has two root ports, it shares most probing flow with the
legacy controller. But the read/write config space logical is different
from the lagacy controller.
This patchset abstract the common probing flow, and add support for the
new generation controller.
Changes since v1:
- Fix build warnings in arm arch.
- Using SoC specific compatible instead of generic compatible.
- Add devicetree binding example for mt7622.
- Unified the register define names with PCIE_ prefix.
- Cleanup some un-necessary condition determine when starup port.
- minor code cleanups.
