Disable USB2 in AMD8111 and remove ide hardcode io addr

[YhLu]

Ron,

I'm going to add several lines in amd8111_enable of amd8111.c to disable
USB2 in amd8111.

/* disable usb2 in amd 8111 because it does not work awlays*/
        byte = pci_read_config8(lpc_dev, 0x47);
        byte |= (1<<7);
        pci_write_config8(lpc_dev, 0x47, byte);

Also will remove several lines in amd8111_ide.c

/* The AMD768 has a bug where the BM DMA address must be
         * 256 byte aligned while it is only 16 bytes long.
         * Hard code this to a valid address below 0x1000
         * where automatic port address assignment starts.
         * FIXME: I assume the 8111 does the same thing. We should
         * clarify. [e-mail]
         */
        pci_write_config32(dev, 0x20, 0xf01);

pci_write_config32(dev, 0x48, 0x205e5e5e);
        word = 0x06a;
        pci_write_config16(dev, 0x4c, word);

and add

byte = 0x20 ; // Latency: 64-->32
        pci_write_config8(dev, 0xd, byte);

regards
