Subject: [PATCH] drm/amdgpu: Copy MEC FW version to MEC2 if we skipped loading MEC2

If we skipped loading MEC2 firmware separately from MEC, then
MEC2 will be running the same firmware image. Copy the MEC version and feature numbers into MEC2 version and feature numbers. This is needed for things like GWS support, where we rely on knowing what version of firmware is running on MEC2. Leaving these MEC2 entries blank breaks our ability to version-check enables and workarounds.
