Daniel Vetter 873af5d888 drm/i915: Bail out of pipe config compute loop on LPT 
commit 2700818ac9 upstream.

LPT is pch, so might run into the fdi bandwidth constraint (especially
since it has only 2 lanes). But right now we just force pipe_bpp back
to 24, resulting in a nice loop (which we bail out with a loud
WARN_ON). Fix this.
