[PATCH] drm/amd/amdgpu: fix build failure due to implicit declaration

[Sudip Mukherjee]

The builds for alpha and mips allmodconfig fails with the error:

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]

drivers/gpu/drm/amd/amdgpu/psp_v13_0.c:534:21:
  error: assignment to 'void *' from 'int' makes pointer from integer
  without a cast [-Werror=int-conversion]

drivers/gpu/drm/amd/amdgpu/psp_v13_0.c:545:33: error: implicit declaration
  of function 'vfree'; did you mean 'kvfree'?
  [-Werror=implicit-function-declaration]

Add the header file for vmalloc and vfree.
