Add ap->orig_sata_spd_limit and initialize it once during the boot initialization (or driver load initialization). ap->sata_spd_limit is reset to ap->orig_sata_spd_limit on hotplug.

Rather than "orig_" call it "hw_" or similar. This is similar to the block layer's max_sectors and max_hw_sectors situation.
