drivers/gpu/drm/i915/intel_pm.c:4655:6: warning: variable 'trans_min' is used
uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
if (INTEL_GEN(dev_priv) >= 10)
but fortunately for us we skip the function unless on a gen10+ device.
However, to keep the function generic in case we do want to re-enable it
for gen9 again, initialise trans_min to 0.
