Subject: [PATCH 04/20] intel_th: gth: Remove commented-out code

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.
