[QUEUED v20160212 03/19] intel_th: gth: Remove commented-out code

From: Alexander Shishkin
Date: Fri Feb 12 2016 - 12:03:10 EST


There's a commented-out function in the GTH driver that's a leftover
from previous versions of the driver, where we tried to inherit the
pre-existing configuration, which didn't prove to be a sound idea.

This patch removes the function. No functional changes.
