[PATCH] drm/amd/pm: Avoid more large frame warnings

[Palmer Dabbelt]

From: Palmer Dabbelt <palmer at dabbelt.com>

9KiB frames seem pretty big, but without this I'm getting some warnings
as of 6.16-rc1

      CC [M]  drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu13/smu_v13_0_6_ppt.o
    drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu13/smu_v13_0_6_ppt.c: In function 'smu_v13_0_6_get_gpu_metrics':
    drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu13/smu_v13_0_6_ppt.c:2885:1: error: the frame size of 8304 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
     2885 | }
          | ^
    cc1: all warnings being treated as errors
