drm/i915: parse eDP panel color depth from VBT block
originally introduced parsing bpp for eDP from VBT, with a default of 18
bpp if the eDP BIOS data block is not present. Turns out that default seems
to break the Macbook Pro with retina display, as noted in
commit 4344b813f105a19f793f1fd93ad775b784648b95

drm/i915: ignore eDP bpc settings from vbt
Since we can't ignore bpc settings from VBT completely after all, get rid
of the default. Do not clamp eDP to 18 bpp by default if the eDP BDB is
missing from VBT.
