fixed patch

I fixed the patch and can apply it on top of amd-drm-next and vanilla kernel
5.0.11 (my current kernel). Unfortunately it doesn't help. I added 'verbose
debug' patch too, here is my output.

1) Before applying high memory profile workaround:
 kernel: amdgpu: [powerplay] min_core_set_clock: 30000
 kernel: amdgpu: [powerplay] min_mem_set_clock: 30000
 kernel: amdgpu: [powerplay] vrefresh: 75

 kernel: amdgpu: [powerplay] performance level 0 memory clock =3D 30000
 kernel: amdgpu: [powerplay] performance level 0 engine clock =3D 30000
 kernel: amdgpu: [powerplay] performance level 1 memory clock =3D 200000
 kernel: amdgpu: [powerplay] performance level 1 engine clock =3D 136600
 kernel: amdgpu: [powerplay] mclk_latency_table entry0 frequency =3D 30000
 kernel: amdgpu: [powerplay] mclk_latency_table entry0 latency =3D 330
 kernel: amdgpu: [powerplay] mclk_latency_table entry1 frequency =3D 100000
 kernel: amdgpu: [powerplay] mclk_latency_table entry1 latency =3D 330
 kernel: amdgpu: [powerplay] mclk_latency_table entry2 frequency =3D 200000
 kernel: amdgpu: [powerplay] mclk_latency_table entry2 latency =3D 330

2) After:

kernel: amdgpu: [powerplay] mclk_latency_table entry2 frequency =3D 200000
kernel: amdgpu: [powerplay] mclk_latency_table entry2 latency =3D 330
