Wolfram Sang d69362f55f drm/bridge: ti-sn65dsi86: Check bridge connection failure 
Read out and check the ID registers, so we can bail out if I2C
communication does not work or if the device is unknown. Tested on a
Renesas GrayHawk board (R-Car V4M) by using a wrong I2C address and by
not enabling RuntimePM for the device.
