drm/bridge: ti-sn65dsi86: Config number of DP lanes Mo' Betta
The driver used to say that the value to program into bridge register
0x93 was dp_lanes - 1. Looking at the datasheet for the bridge, this
is wrong. The data sheet says:
* 1 = 1 lane
* 2 = 2 lanes
* 3 = 4 lanes
A more proper way to express this encoding is min(dp_lanes, 3).
At the moment this change has zero effect because we've hardcoded the
number of DP lanes to 4. ...and (4 - 1) == min(4, 3). How fortunate!
...but soon we'll stop hardcoding the number of lanes.
