"Manual GPU Clock Control" is nonfunctional

[jerbmega]

On SteamOS, the Manual GPU Clock Control option brings up a slider where the GPU clockspeed can be forced to a specific value with a slider. On Bazzite, enabling this option never shows its respective slider.

This may be similar to my comment in #58, or simply a needed karg to allow clock controls. Looking into this. Thanks for the report!

If anyone else wants to test this, two things to try:

1. Disable SELinux temporarily with sudo setenforce 0, re-enable with sudo setenforce 1.
2. Enable advanced clock control in amdgpu with: rpm-ostree kargs --append="amdgpu.ppfeaturemask=0xffffffff" followed by rebooting.

SELinux set to permissive and that karg set doesn't seem to change anything on my end.
