[Bug 2169534] [NEW] [SRU] Fix NPU errors on Gorgon Halo

Public bug reported: BugLink: [ Impact ] To enable NPU on Gorgon Halo, a new ID needs to be added to the revision list in the driver. Otherwise the amdxdna driver would show the following error message: [ 2.996014] test kernel: amdxdna 0000:c5:00.1: [drm] *ERROR* aie2_get_dev_revision: Unknown device revision: 9 (raw fuse: 0x10170) [ Fix ] Cherry-pick the following patch: - [PATCH V2] accel/amdxdna: Add support for AIE2 revision 9[1] This patch is currently in the linux-next tree as commit 63e91c1997898f32f68a5dbf68195d68b8e58443 since next-20260930 [ Test plan ] Boot the kernel. The driver should recognize the NPU, showing the following message instead: [ 3.130089] test kernel: [drm] Initialized amdxdna_accel_driver 0.10.0 for 0000:c5:00.1 on minor 0 [ Where problems could occur ] Unless there are conflicts in the IDs, this only makes the driver bind to a superset of already-supported hardware, so this shouldn't impact existing hardware support.
