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

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

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:

is locked in that state)

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.
