    libata: implement and use sata_std_hardreset() · 57c9efdf
    Tejun Heo authored
    Implement sata_std_hardreset(), which simply wraps around
    sata_link_hardreset().  sata_std_hardreset() becomes new standard
    hardreset method for sata_port_ops and sata_sff_hardreset() moves from
    ata_base_port_ops to ata_sff_port_ops, which is where it really
    belongs.
    
    ata_is_builtin_hardreset() is added so that both
    ata_std_error_handler() and ata_sff_error_handler() skip both builtin
    hardresets if SCR isn't accessible.
    
    piix_sidpr_hardreset() in ata_piix.c is identical to
    sata_std_hardreset() in functionality and got replaced with the
    standard function.
