drm/i915: Replace intel_bios_is_lane_reversal_needed() with intel_bios_encoder_lane_reversal()

The sole user of intel_bios_is_lane_reversal_needed() has
the devdata already located, so pass it in directly instead
of digging it again from vbt.ports[].

And rename the function to follow the common pattern for
these things.
