[PATCH v2 2/2] drm/amd: Don't wake dGPUs while reading sensors

[Mario Limonciello]

If the dGPU is off, then reading the sysfs files with a sensor monitoring
application will wake it. Change the behavior to return an error when the
dGPU is in runtime PM.  Leave the behavior the same for debugfs files.
