Paulo Zanoni ba8ee59850 drm/i915: fix DDI PLLs HW state readout code ...

commit 0882dae983 upstream.

Properly zero the refcounts and crtc->ddi_pll_set so the previous HW
state doesn't affect the result of reading the current HW state.

This fixes WARNs about WRPLL refcount if we have an HDMI monitor on
HSW and then suspend/resume.
