xrandr output showing the 60hz support

After 4.18 didn't have support for 4k at 60hz over HDMI, it was refreshing to see
it supported in amd-staging-drm-next. Unfortunately, there is currently high
pitch audio when using 4k at 60 output. Using xrandr to change to any other
resolution or refresh rate has fully working audio.

I understand Polaris is still very WIP hardware, but I'm willing to test
patches or get additional logging to help with this bug.
