Change AMD overclocking to simply be setting the power_dpm_force_performance_level file for now

This covers the MVP for now, and simply allows pinning the power level to "high"

	Full overclocking set up is somewhat more complicated, and it'll be better to implement that at the same time as the same for Nvidia, where we're currently only really setting the top end power level
