tools/power turbostat: show GFXMHz
Under the column "GFXMHz", show a snapshot of this attribute:
/sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz
This is an instantaneous snapshot of what sysfs presents
at the end of the measurement interval. turbostat does
not average or otherwise perform any math on this value.
