commit e83bf69e7a3ba8e1dd7e438781d16af73adff0cf

Fix AMD UMA for RS780
In commit 6b5eb1cc2d1702ff10cd02249d3d861c094f9118 setup of
UMA memory region was moved to happen at a later state and
this broke UMA with RS780 southbridge.
Share the TOP_MEM and UMA settings before any of the PCI or CPU
scanning takes place.
