    i82801gx: Fix port status in AHCI mode
    
    The code used PCI register 0x92 to enable sata ports,
    which is wrong. The ICH7 documentation states:
    
    "This register is only used in systems that do not
    support AHCI. In AHCI enabled systems, bits[3:0] must
    always be set (ICH7R only) / bits[2,0] must always be set
    (Mobile only), and the status of the port is controlled
    through AHCI memory space."
    
    Writing 0x0f to ICH7-M doesn't seem to hurt, so lets write
    0x0f for both variants. This patch makes sata_ahci work on
    my Thinkpad T60 and X60s.
