[PATCH] drm/amd/amdgpu: add complete header search path

[Randy Dunlap]

The path for the "mod_info_packet.h" header file is
incomplete, so add its location to the header search path
in the amdgpu Makefile.

See on ARCH=alpha (275 times in one build).

In file included from ../drivers/gpu/drm/amd/amdgpu/amdgpu.h:90,
                 from ../drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:43:
../drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.h:62:10: fatal error: mod_info_packet.h: No such file or directory
   62 | #include "mod_info_packet.h"
