GPU hang 13 - after media encoder power gating ONLY enabled

At least 3 compute sticks died when run in this configuration and I uploaded
#12 previously. 

+               gen9_disable_rc6(dev_priv);
+
+               I915_WRITE(GEN9_PG_ENABLE,
+                          GEN9_MEDIA_PG_ENABLE);

This particular crash had a huge amount of information dumped, so I figured I
should upload it also.

Interestingly, the compute stick which usually has its GPU hang for all these
tests is still running strong after 839 iterations.

I am about to test the opposite power gate and see if the render power gate ON
while media power gate is OFF has any effect.
