tools/power/turbostat: Support alternative graphics sysfs knobs

Browse source

/sys/class/graphics/fb0/device/drm/card0/ and /sys/class/drm/card0/
point to the same device node.
But in some cases, one exists and the other one does not.

Prefer to use /sys/class/drm/card0/, and fall back to
/sys/class/graphics/fb0/device/drm/card0/.

This recovers the "GFXMHz" and "GFXAMHz" columns on some platforms like
a SPR server.
