tools/power/turbostat: Add support for new i915 sysfs knobs
On Meteorlake platform, i915 driver supports the traditional graphics sysfs knobs including /sys/class/drm/card0/power/rc6_residency_ms /sys/class/drm/card0/gt_cur_freq_mhz /sys/class/drm/card0/gt_act_freq_mhz At the same time, it also supports /sys/class/drm/card0/gt/gt0/rc6_residency_ms /sys/class/drm/card0/gt/gt0/rps_cur_freq_mhz /sys/class/drm/card0/gt/gt0/rps_act_freq_mhz /sys/class/drm/card0/gt/gt1/rc6_residency_ms /sys/class/drm/card0/gt/gt1/rps_cur_freq_mhz /sys/class/drm/card0/gt/gt1/rps_act_freq_mhz gt0 is for GFX and gt1 is for SA Media. Enhance turbostat to prefer the i915 new sysfs knobs. Export gt0 via BIC_GFX_rc6/BIC_GFXMHz/BIC_GFXACTMHz. Export gt1 via BIC_SMA_mc6/BIC_SMAMHz/BIC_SMAACTMHz.
