[ Upstream commit 4c06d35dfedf4c1fd03702e0f05292a69d020e21 ]
It was lately understood that the current mechanism available in the driver to get SMU firmware info works only on internal SMU builds and there is a separate way to get all the SMU logging counters (addressed in the next patch). Hence remove all the smu info shown via debugfs as it is no more useful.
