[PATCH v2 1/2] dt-bindings: PCI: xilinx-cpm: Add compatible string for CPM5 controller 1

[Thippeswamy Havalige]

The Xilinx Versal Premium series includes the CPM5 block, which supports
two Type-A Root Port controllers operating at Gen5 speed.

This patch adds a compatible string to distinguish between the two CPM5
Root Port controllers. The error interrupt registers and corresponding bits
for Controller 0 and Controller 1 are located at different offsets, making
it necessary to differentiate them.

By using the new compatible string, the driver can properly handle these
platform-specific differences between the controllers.
