mb/asus/h61m-cs: Add ASUS H61M-CS

Working:
 - USB (Partially. Check "Not working")
 - PCIe
 - PCIe graphics
 - All SATA ports
 - Native memory init
 - On-board audio (back and front)
 - S3 (Sleep and wake)

Not working:
 - Fan control
 - USB (If the keyboard has a USB Hub or if the keyboard
        is connected through 2 or more hubs then it doesn't
        initialize in time. A simple reboot allows the
        keyboard to be used in SeaBIOS and the bootloader)

Untested:
 - PS/2
 - On board graphics
