    Revert "drm/i915: revert eDP bpp clamping code changes"
    
    This reverts commit 57c219633275c7e7413f8bc7be250dc092887458.
    
    It's an ugly hack for a Haswell SDV platform where the vbt doesn't
    seem to fully agree with the panel. Since it seems to cause issues on
    real eDP platform let's just kill this hack again.

I'll investigate a bit, but this is not exactly my expertise.

Title:
  Installation, Live and Check disc do not start on Asus ZenBook Prime
  UX31A

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” source package in Raring:
  Confirmed
Status in “linux” source package in Saucy:
  Incomplete

Bug description:
  When I try to install Ubuntu 13.04 on a new Asus ZenBook Prime UX31A
  from june 2013, grub will come up bit every option such as
  Installation, Live and Check disc result in a blank screen. This is
  possibly due to preinstalled Windows 8 and UEFI.

  I did not approve/accept the Windows 8 installation and that should
  not matter. I want to install only Ubuntu and *no* dual boot with the
  preinstalled Windows 8. I want to erase the entire disc in firsts
  steps of installation procedure.

  Screenshot illustrating the problem are:

  Debugging attempts from
  https://wiki.archlinux.org/index.php/Boot_Debugging failed. Perhaps I
  did something wrong. What are ways to write debug to the screen in my
  case?

  And, more importantly, how do I get it working because have the right
  to install whatever I want?

  Is the only way to get it installed to accept the Windows 8 license
  and install Ubuntu from Windows (and in effect making it dual boot
  which I don't want).

  Ubuntu should fix this as it is the flagship of a major laptop
  manufacturer (ASUS) for which Ubuntu is no longer installable.
