drm/i915: Clean up LVDS register handling harder

Browse Source 
Minor fixup to d0669d0075 ("drm/i915: Clean up LVDS register
handling") which intended to read lvds_reg just once at the
beginning of intel_lvds_init() and use that throughout the rest
of the function but accidentally missed one register readout.
