[PATCH 09/15] drm/i915: remove additional zerogin of VLV_IIR at postinstall

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

There is no comment explaining why it's needed and I don't see a
reason for it to exist. Also, a few lines above we call
INTEL_IRQ_REG_INIT and pass VLV_IIR, so we should print a WARN in case
VLV_IIR is not zero at that point.
