test/amdgpu/hotunplug: Add test suite for GPU unplug
Add plug/unplug device and open/close device file infrastructure. Add basic test - unplug device while device file still open. Close device file afterwards and replug the device. Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Reviewed-by: Alex Deucher alexander.deucher@amd.commain
