This property is the only one used for this IP, I have compared this IP with
other DPHY rx module, DPHY modules form the other manufacturers not have this
configure.
And we also have a SoC called JH7100. It DPHY rx module is the same as JH7110.
But we don't do the upstream work on it. If it use this lane-maps will be
configure as "lane_maps = /bits/ 8 <0 1 2 3 4 5>;".
So what do you think? Can this configure be implemented into a property?
