drm/i915: Add missing MacBook Pro models with dual channel LVDS ...
Single channel LVDS maxes out at 112 MHz. The 15" pre-retina models
shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz)
as a BTO option, both versions used dual channel LVDS even though
the smaller one would have fit into a single channel.
Notes:
Bug report showing that the MacBookPro8,2 with 1440x900 uses dual
channel LVDS (this lead to it being hardcoded in intel_lvds.c by
Daniel Vetter with commit 618563e394https://bugzilla.kernel.org/show_bug.cgi?id=42842
If i915.lvds_channel_mode=2 is missing even though the machine needs
it, every other vertical line is white and consequently, only the left
half of the screen is visible (verified by myself on a MacBookPro9,1).
Forum posting concerning a MacBookPro6,2 with 1440x900, author is
using i915.lvds_channel_mode=2 on the kernel command line, proving
that the machine uses dual channels:
https://bbs.archlinux.org/viewtopic.php?id=185770
Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all
MacBook Pro "A1286" models, and that model number encompasses the
MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's
driven with dual channel LVDS:

http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286
http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf
Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones
with i915 graphics and dual channel LVDS, so that list should be
complete. And the 8,2 is already in intel_lvds.c.
Possible motivation to use dual channel LVDS even on the 1440x900
models: Reduce the number of different parts, i.e. use identical logic
boards and display cabling on both versions and the only differing
component is the panel.
