Linux 4.18-rc5+ messages with trace from `power_down_all_hw_blocks`

Here is another trace from `power_down_all_hw_blocks()`. Please note, the UEFI
firmware didn’t initialize the DP connected monitor correctly and the
framebuffer was just black until amdgpu loaded. Please tell me, if I should
create a separate bug for that.
