This series extends amdxdna with initial support for AIE4 Virtual Functions
and the user-visible execution path.
Move message buffer allocation and device metadata collection to aie.c,
allowing both AIE2 and AIE4 devices to reuse common code.
Testing:
PF + VF: Probe AIE4 PF, enable SR-IOV, bind VF devices, and run
end-to-end workloads from a userspace application.
Regression: Validate existing AIE2 regression tests.
