siemens/mc_apl1: Activate PTN3460 eDP to LVDS bridge IC

This mainboard uses a LVDS connection for LCD panels. Apollo Lake SoC
provides a display controller with three independent pipes (1x eDP and
2x DP/HDMI). PTN3460 is an embedded DisplayPort to LVDS bridge device
that enables connectivity between an eDP source and LVDS display panel
(http://www.nxp.com/documents/data_sheet/PTN3460.pdf).
The bridge contains an On-chip Extended Display Identification Data
(EDIT) emulation for EDIT data structures.
This patch sets up PTN3460 to be used with the appropriate LCD panel.
