sata: ahci: export ahci_do_hardreset() locally
We need a way to retrieve the information about the online state of
the link in the ahci-da850 driver.
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.
