Subject: [PATCH] drm/amdgpu: add function declaration in amdgpu.h

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/sdma_v3_0.c:502:10: warning: no previous prototype for 'init_cond_exec' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/sdma_v3_0.c:514:6: warning: no previous prototype for 'patch_cond_exec' [-Wmissing-prototypes]

In fact, both functions are not declared in any files.

So this patch declares them in drivers/gpu/drm/amd/amdgpu/amdgpu.h.
