drm/i915: do not ignore eDP bpc settings from vbt

commit 2f4f649a69a9eb51f6e98130e19dd90a260a4145 upstream.

There are laptops out there that need the eDP bpc from VBT. This is

    drm/i915: ignore eDP bpc settings from vbt

but putting the VBT check after the EDID check to see them both in dmesg if

warrant the extra debug info.
