drm/i915: save/restore GMBUS freq across suspend/resume on gen4
commit 9f49c37635d5c2a801f7670d5fbf0b25ec461f2c upstream.
Should probably just init this in the GMbus code all the time, based on
the cdclk and HPLL like we do on newer platforms. Ville has code for
that in a rework branch, but until then we can fix this bug fairly
easily.
