[Intel-gfx] [PATCH 3/3] drm/i915: don't ironlake_init_pch_refclk() on LPT

[Paulo Zanoni]

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

This function is used to set the PCH_DREF_CONTROL register, which does
not exist on LPT anymore.

My crystal ball tells me patches like this will become more and more
common in the future... That's why patch 01 was proposed.

This patch depends on patch 01, otherwise we'll start calling
ironlake_init_pch_refclk on non-pch machines.
