    mainboard/bap/ode_e20XX: Change SATA from GEN2 to GEN3
    
    This patch disables the SataSetMaxGen2 flag.
    This flag is a power saving option,
    which forces the SATA to GEN2.
    Payload SeaBIOS 1.9.1, Lubuntu 16.04, Kernel 4.4.
    $ dmesg | grep ahci #before patch

    $ dmesg | grep ahci #after patch
    ahci 0000:00:11.0: AHCI 0001.0300 32 slots 2 ports 6 Gbps 0x3 impl SATA mode
