[PATCH 08/14] drm/amdgpu: add gfx v9.4.3 ACA support

[Zhang, Hawking]

[AMD Official Use Only - General]

Simiar as patch #9 and #10, let's use macro to define the magic numbers

+       case 0x36430400: /* SMNAID XCD 0 */
+       case 0x38430400: /* SMNAID XCD 1 */
+       case 0x40430400: /* SMNXCD XCD 0, NOTE: FIXME: fix this error later */

Regards,
Hawking
