Michael Wright 4e1bf7e542 Fix autobrightness control points.
The control points from another device were directly copied over to
Taimen, but Taimen's display's display has a very different mapping
between backlight value and actual produced brightness. These new values
bring it inline without our ML learned curve compensating for this fact.

The one difference here is that Taimen can go brighter than the devices
the model was trained on so an additional point was introduced. Based on
visual inspection the curve looks almost exactly linear in the last few
points before it hits the ceiling, so the final point is just a linear
extrapolation from Marlin's final two control points to Taimen's maximum
brightness.

Note also that Taimen's display can't be set above 223 in normal use.
Every value about this is an "overdrive" setting and greatly increases
the risk of burn-in not to mention using significantly more power.
