Add support for MA785GM-US2H

This patch adds coreboot support for the
GIGABYTE MA785GM-US2H board.

This port now removes all dead code in
the previous patch set, and also boots Fedora 16
on x86_64 (Phenom II X4 955 BE)

On-board audio causes spurious interrupts and
the kernel gets stuck in an infinite loop.

AtomBIOS on RadeonHD video cards does not function
and causes another infinite loop. radeon.modeset=0
must be set. acpi=off must also be set.

With those kernel command line options set,
Fedora 16 makes it to the login screen. USB
mouse and keyboard don't work though. several
USB error codes on boot-up. PS/2 should.

+ * BOOL AMD_CB_ManualBUIDSwapList(u8 Node, u8 Link, u8 **List)
+ * Description:
+ *	This routine is called every time a non-coherent chain is processed.
+ *	BUID assignment may be controlled explicitly on a non-coherent chain. Provide a
+ *	swap list. The first part of the list controls the BUID assignment and the
+ *	second part of the list provides the device to device linking.  Device orientation
+ *	can be detected automatically, or explicitly.  See documentation for more details.
+ *
+ *	Automatic non-coherent init assigns BUIDs starting at 1 and incrementing sequentially
+ *	based on each device's unit count.
+ *
+ * Parameters:
+ *	@param[in]  u8  node    = The node on which this chain is located
+ *	@param[in]  u8  link    = The link on the host for this chain
+ *	@param[out] u8** list   = supply a pointer to a list
+ *	@param[out] BOOL result = true to use a manual list
+ *				  false to initialize the link automatically
+ */
