Alan Cox c5038fc05d libata/pata_it821x: Improve handling of poorly compatible emulations 
Some it821x RAID firmwares return 0 for the err return off both devices.
A similar issue occurs with the slave returning 0 not 1 if you plug a
gigabyte sata ramdisk into a controller that fakes two SATA ports as
master/slave on an SFF channel.

The patch does the following

- Allow the 'failed diagnostics' case on both master and slave
- Move the HORKAGE_DIAGNOSTIC check after ->dev_config

This second change also allows IT821x to fix up a problem where we report
drive diagnostic failures when in fact the drive is fine but the
microcontroller firmware doesn't appear to get it right. IT821x clears
the flag again to avoid giving the user bogus warnings about their disk.

The other IT821x change is a bit ugly, we slightly abuse the cable type
hook to fiddle with the identify data for the devices. We could add a new
hook for this but as we have only one offender and no more seeming likely
it seems better to keep libata-core clean.

Please let this sit in -mm briefly, just in case the relaxed checking
breaks some other emulated interface.
