Introduce an ASPEED PCIe Root Port and wire it under the RC. The root port
is modeled as TYPE_ASPEED_PCIE_ROOT_PORT (subclass of TYPE_PCIE_ROOT_PORT).
Key changes:
- Add TYPE_ASPEED_PCIE_ROOT_PORT (PCIESlot-based) with vendor/device IDs
and AER capability offset.
- Extend AspeedPCIERcState to embed a root_port instance and a
configurable rp_addr.
- Add "rp-addr" property to the RC to place the root port at a specific
devfn on the root bus.
- Set the root port's "chassis" property to ensure a unique chassis per RC.
- Extend AspeedPCIECfgClass with rc_rp_addr defaulting to PCI_DEVFN(8,0).
Rationale:
- AST2600 places the root port at 80:08.0 (bus 0x80, dev 8, fn 0).
- AST2700 must place the root port at 00:00.0, and it supports three RCs.
Each root port must therefore be uniquely identifiable; uses the
PCIe "chassis" ID for that.
- Providing a configurable "rp-addr" lets platforms select the correct
devfn per SoC family, while the "chassis" property ensures uniqueness
across multiple RC instances on AST2700.
