This patch adds support for mainboard iBASE:MB899

based on Kontron 986LCD-M
changed superIO chip to w83627ehg, dropping MIDI
dropped second superIO at 4e
changed superIO-addr from 2e to 4e
adjusted irq_tables.c and devicetree.cb
dropped setup of 3xGBit-Ethernet
adjusted IRQ-map (using values from mainboard/intel/d945gclf)
disabled parts about HD-audio (missing on that board)
