IDE probing code used to skip devices attached to EATA SCSI HBA
in ATA emulating mode but because of warm-plug support port I/O
resources are no longer freed if no devices are detected on a port
and the decision about the driver to use is left up to the user.

Remove no longer valid EATA SCSI HBA quirk from do_identify().

cdrom_read_capacity() will blindly return the capacity from the device
without sanity-checking it.  This later causes code in fs/buffer.c to
oops.

Fix this by checking that the device is telling us sensible things.

This controller supports UltraDMA up to mode 5 but it should be clocked with
at least twice the data strobe frequency, so enable mode 5 for 100+ MHz IDECLK.

Prefix messages from IDE PCI host drivers by driver name instead of marketed
chipset name (it is still possible to exactly identify the particular chipset
basing on driver messages).

As a bonus this provides nice code savings for some drivers:
