This patch set adds PCIe Root Port support for the Agilex family of FPGA chips.
Version 6 refactors duplicate dts snippets into dtsi's for correctness and
maintainability.

Patch 1:
  Add new compatible strings for the three variants of the Agilex PCIe controller IP.

Patch 2:
  Add new board compatible string for Agilex F-series devkit with PCIe Root Port.

Patch 3:
  Fix fixed-clock schema warnings in socfpga_agilex.dtsi before adding to it.

Patch 4:
  Move bus@80000000 dt node to socfpga_agilex.dtsi.

Patch 5:
  Add base dtsi for PCIe Root Port support of the Agilex family of chips.

Patch 6:
  Add dts enabling PCIe Root Port support on an Agilex F-series Development Kit.

Patch 7:
  Update Altera PCIe controller driver to support the Agilex family of chips.
