drm/i915: Kill leftover GTIIR writes from valleyview_irq_preinstall()

There are two leftover GTIIR writes in valleyview_irq_preinstall().
Looks like the were originally left behind by:

    drm/i915: unify PM interrupt preinstall sequence

and then the GTIIR reset was added back here:

    drm/i915: properly clear IIR at irq_uninstall on Gen5+

so we can kill the leftovers from the vlv code.
