Subject: drm/amdgpu: change memory training to common function
Git-commit: 963cee55971a1c41972518f7e0e581f01e5f8b7b
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Change memory training init and finit a common function, as it only have
software behavior do not relay on the IP version of PSP.
