OneXPlayer idle-power tuning

This host policy combines aggressive runtime idle power management with full AMD CPU boost availability. The three locally identified USB input devices are left alone so the built-in controller, keyboard, and receiver wake instantly.

The system service applies PCI runtime PM, a 625 MHz CPU floor, the full 5.19 GHz boost ceiling, balance_power EPP, and less frequent dirty-page wakeups. The resume hook reapplies those settings after suspend.

Power Profiles reports performance because that firmware profile is required to expose the full boost ceiling. The service then replaces its CPU floor and EPP values, so the effective policy is the custom low-idle configuration above.

The NetworkManager drop-in enables Wi-Fi power saving by default. Installation reloads NetworkManager configuration; reconnect Wi-Fi to apply it to an already-active connection.

oxp-cpu-profile exposes the effective custom mode as adaptive and is used by the OXP Control GNOME extension's CPU Power menu. Selecting Adaptive asks for administrator authorization and reapplies oxp-idle-power.service.

Ultra Saver keeps the 625 MHz floor, caps the CPU at its 2.0 GHz lowest non-linear (most efficient) frequency, and selects the power EPP hint. The other modes restore the CPU's full hardware frequency range before applying their profile, so leaving Ultra Saver cannot retain its 2.0 GHz ceiling. The selected OXP mode is stored in /var/lib/oxp-power-mode and restored at boot and after resume.

The internal unsupported FocalTech 2808:5952 fingerprint reader is disabled at its dedicated USB port. A device-specific udev rule reapplies the setting after USB controller re-enumeration; the power service also reapplies it after resume.
