[PATCH] drm/rockchip: lvds: do not dig into the DT of remote bridges

[Peter Rosin]

The driver is trying to find the needed "data-mapping" for
interacting with the following bridge in the graphics chain.
But, doing so is bad since it is done w/o regard of the
compatible of the remote bridge, so the value of "data-mapping"
might not mean what this driver assumes. It is also pointless
since no bridge has any documented "data-mapping" DT property
and no dts file show any undocumented use.

Just remove the inappropriate code.
