ide: move restart callback to common code

With BMDMA specific excised from the restart functions,
create a HBA-agnostic restart callback to be shared
between the different HBAs.

Change the callback registered with the vmstate_change
handler to always point to ide_restart_cb instead of
relying on the IDEDMAOps.restart_cb() member.
