drm/i915/dsi: Do not clear DPOUNIT_CLOCK_GATE_DISABLE from
vlv_init_display_clock_gating

Hi,

I've been seeing this same issue on another cherrytrail tablet. After working
on debugging this more or less every evening for about a week, I believe I now
have a fix :)

Can you please build a recent kernel with the attached patch and see if that
fixes this for you ?

Regards,

Hans
