Jesse Barnes ea88728a1d drm/i915/vlv: remove wait for previous GFX clk disable request 
commit 5df0582bf0 upstream.

Looks like it was introduced in:

commit 650ad970a3
Author: Imre Deak <imre.deak@intel.com>
Date:   Fri Apr 18 16:35:02 2014 +0300

    drm/i915: vlv: factor out vlv_force_gfx_clock and check for pending force-of

but I'm not sure why.  It has caused problems for us in the past (see
85250ddff7 "drm/i915/chv: Remove Wait for a previous gfx force-off"
and 8d4eee9cd7 "drm/i915: vlv: increase timeout when forcing on the
GFX clock") and doesn't seem to be required, so let's just drop it.
