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.

Please just add @online to ahci_hardreset() and update the callers.
Other than that, the sata changes look good to me.

Are you sure? There are 23 places in drivers/ata/ where the .hardreset
callback is assigned. I'd prefer not to change the drivers I can't
test. Besides all other **reset callbacks take three arguments -
should we really only change one of them for a single driver's needs?

Thanks,
Bartosz
