[Intel-gfx] [PATCH 2/6] drm/i915: Pass explicit mode into mode_from_pipe_config v3

[Jesse Barnes]

From: Daniel Vetter <daniel.vetter at ffwll.ch>

We want to reuse this in the fbdev initial config code independently
from any fastboot hacks. So allow a bit more flexibility.

v2: Forgot to git add ...
v3: make non-static (Jesse)
