[PATCH 2/2] PCI: amd-mdb: Add amd,versal2-cpm6-host compatible

[Sai Krishna Musham <sai.krishna.musham@amd.com>]

Add "amd,versal2-cpm6-host" to the OF match table of the AMD MDB PCIe
host controller driver.

The Versal2 CPM6 host controller is DesignWare-based and supports
PCIe Gen6 operation at up to 64 GT/s per lane. It is currently
handled by the same driver and match data (NULL) as the existing
MDB host controller, but CPM6 uses a newer IP revision and differs
in legacy INTx register offsets.

Use a separate compatible to allow CPM6-specific handling once legacy
interrupt support is validated.
