drm/i915: Bail out of pipe config compute loop on LPT
commit 2700818ac9f935d8590715eecd7e8cadbca552b6 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.
