Peter Marheine 059f56e6ce realtek-mst: add support for RTD2141B
The RTD2141B has the same update protocol as RTD2142, but the Chromebook
targets that use it require us to find the drm_dp_aux_dev i2c channel
differently because the AMD display driver doesn't give each output a
unique name in sysfs, so it must be found by walking sysfs from the drm
device representing an output.
