drm/i915: Split map_aux_ch() into per-platform arrays
The big switch+if statement mess in map_aux_ch() is
illegible. Split up into cleaner per-platform arrays
like we already have for the gmbus pins.
We use enum aux_ch as the index and the VBT thing as
the value. Slightly non-intuitive perhaps but if we
did it the other way around we'd have problems with
AUX_CH_A being zero, and thus any non-populated
element would look like AUX_CH_A.
v2: flip the index vs. value around
TODO: Didn't bother with the platform variants beyond the
ones that really need remapping, which means if the
VBT is bogus we end up with a nonexistent aux ch.
Might be nice to check this a bit better.
Yet another bitmask in device info?
