vt6420 completely loses its ability to raise IRQ for ATAPI devices if
ATA_NIEN is diddled with in ->freeze. Further investigation is
necessary to determine whether this problem is shared on other
controllers but it doesn't seem to be at this point.
Make vt6420's ->freeze only clear IRQ to fix this problem. This makes
vt6420 relatively more prone to IRQ storms but the controller is way
too braindamaged to worry about that anyway.

The biggest change is that ata_host_set is renamed to ata_host.
* ata_host_set => ata_host
* ata_probe_ent->host_flags => ata_probe_ent->port_flags
* ata_probe_ent->host_set_flags => ata_probe_ent->_host_flags
* ata_host_stats => ata_port_stats
* ata_port->host => ata_port->scsi_host
* ata_port->host_set => ata_port->host
* ata_port_info->host_flags => ata_port_info->flags
* ata_(.*)host_set(.*)\(\) => ata_\1host\2()
The leading underscore in ata_probe_ent->_host_flags is to avoid
reusing ->host_flags for different purpose. Currently, the only user
of the field is libata-bmdma.c and probe_ent itself is scheduled to be
removed.
ata_port->host is reused for different purpose but this field is used
inside libata core proper and of different type.
