 memory training support for PSP_V13")

Hi All,

The latest mainline kernel branch fails to build for alpha and mips
allmodconfig with the error:

drivers/gpu/drm/amd/amdgpu/psp_v13_0.c: In function 'psp_v13_0_memory_training':
drivers/gpu/drm/amd/amdgpu/psp_v13_0.c:534:23: error: implicit declaration of function 'vmalloc'; did you mean 'kvmalloc'? [-Werror=implicit-function-declaration]
  534 |                 buf = vmalloc(sz);
      |                       ^~~~~~~
      |                       kvmalloc

git bisect pointed to 6fdd2077ec03 ("drm/amd/amdgpu: add memory training support for PSP_V13").

And, reverting that commit has fixed the build failure.

I will be happy to test any patch or provide any extra log if needed.
