drm/i915: Check backlight type while doing eDP backlight initializaiton
If LFP backlight type setting from VBT was "VESA eDP AUX Interface".
Driver should check panel capability and try to initialize aux backlight.
No matter i915_modparams.enable_dpcd_backlight was enabled or not.
v2: access dev_priv->vbt.backlight.type directly and remove unused function.
v3: 1. Modify i915.enable_dpcd_backlight type from bool to int and give default
value as 0 (disable).
2. Add a judgement to check LFP backlight type was aux interface or not.
