PCI: cadence: Replace private message routing enums with PCI core definitions
The Cadence driver previously defined its own message routing enums (e.g.,
MSG_ROUTING_LOCAL) and message codes, which duplicated existing PCI core
macros (PCIE_MSG_TYPE_R_LOCAL, PCIE_MSG_CODE_ASSERT_INTA, etc.) in
drivers/pci/pci.h. These core definitions align with the PCIe r6.0 spec.
Remove the driver-specific enums and switch to the centralized PCI core
macros. This eliminates redundancy, ensures consistency, and simplifies
future updates. No functional changes are introduced.
