eric patch

        1. x86_setup_mtrr take address bit.
        2. generic ht, pcix, pcie beidge...
        3. scan bus and reset_bus
        4. ht read ctrl to decide if the ht chain
           is ready
        5. Intel e7520 and e7525 support
        6. new ich5r support
        7. intel sb 6300 support.

yhlu patch
	1. split x86_setup_mtrrs to fixed and var
	2. if (resource->flags & IORESOURCE_FIXED ) return; in device.c pick_largest_resource
	3. in_conherent.c K8_SCAN_PCI_BUS
