Create a new function: ahci_do_hardreset() which is called from ahci_hardreset() for backwards compatibility, but has an additional argument: 'online' - which can be used to check if the link is online after this function returns. The new routine will be used in the ahci-da850 driver to avoid code duplication when implementing a workaround for tha da850 SATA controller quirk/instability.
