drivers/i2c/ptn3460: Provide chip driver for PTN3460

This patch provides a chip driver for the DP-2-LVDS bridge PTN3460.
The bridge is configured via I2C. As the mainboard has all the
information regarding the attached LCD type, there are three hooks into
mainboard code to get the information like EDID data and PTN config.

TEST=Display is working on Siemens mainboards (e.g. mc_tcu3, mc_apl1, ...).
