Subject: [PATCH 5.1 11/55] drm/i915: Remove redundant store of logical CDCLK state

From: Imre Deak <imre.deak@...el.com>

commit 2b21dfbeee725778daed2c3dd45a3fc808176feb upstream.

We copied the original state into the atomic state already earlier in
the function, so no need to do it a second time.
