Subject: [PATCH 1/2] drm/amdgpu: Clarify that TMZ unsupported message is due to hardware

The warning

    amdgpu 0000:05:00.0: amdgpu: Trusted Memory Zone (TMZ) feature not supported

leaves the reader wondering, if anything can be done about it. As it’s
unsupported in the hardware, and nothing can be done about, mention that
in the log message.

    amdgpu 0000:05:00.0: amdgpu: Trusted Memory Zone (TMZ) feature not supported by hardware
