[PATCH] libata-hp-prep: implement ap->hw_sata_spd_limit
Add ap->hw_sata_spd_limit and initialize it once during the boot
initialization (or driver load initialization). ap->sata_spd_limit is
reset to ap->hw_sata_spd_limit on hotplug. This prevents spd limits
introduced by earlier devices from affecting new devices.
