NAK - __ is for internal symbol names.

I was split 50/50 on adding ata_pci_sff_init_one_flags() or similar but
the churn, given its a one off and we can then add all sorts of other
future flags without pain, seemed worth it.

I'm ambivalent about whether its best to go with a new function name as
you have or take the hit now (which seems sensible to me). Either way the
__ naming is wrong for an external interface.

Anyway I'd *hope* we can get > 50% of interfaces parallel scanning at
which point it ceases to be more noise anyway !

Jeff ?
