[PATCH] drm/i915: fix regression after clock gating init split

[Jason Stubbs <jasonbstubbs@gmail.com>]

From: Jason Stubbs <jasonbstubbs@gmail.com>

During the refactoring in revision 6067aaeadb5b3df26f27ac827256b1ef01e674f5,
the intel_enable_clock_gating was split up into several functions that are
then called indirectly. However, which function to call was not specified for
the IS_PINEVIEW() case. This patch specifies the correct gating function.
