mainboard/biostar: Add support for Biostar AM1ML ver7.x
Adds AM1ML board. This board has AM1 Socket and supports all
new AM1 APUs from AMD. Based on asrock/imb-a180 board.
Successfully tested with SeaBIOS and Linux 3.8.x and Windows XP.
Successfully tested audio, video, network, PS/2 keyboard and mouse,
PCIe x16, COM port, SATA and USB.
LPT port is not tested yet and it’s unknown if it’s work.
