mainboard: Add AMD unionstation RDK support

AMD unionstation Reference Design Kit is Designed for hd settop box application.
This platform using family14 APU, SB800 southbridge.
Vgabios is required, can download vgabios from AMD NDA website.
Verified Feature:
 HDMI, LAN, mini-pcie slots, sata, usb, analog audio and
 optical fiber digital audio output.
