Subject: siemens/mc_apl1: Move board specific things to mc_apl1 variant

The following things are specific characteristic of mc_apl1 board
variant:

- initialization for the eDP to LVDS converter
- enable decoding address range for COM 3
- legacy IRQ routing for PCI devices
- wait function for old legacy devices
- set coreboot ready LED
